I am happy to introduce our first isolated power module, which we expect to kick off a new category of electrical isolation products (note that the many current sensors we carry also feature isolation from the sense side to the control side, but that isolation is part of their more dedicated current-sensing functionality). Many of our products are modules like motor controllers and regulator boards, and connecting several of them together in real-world settings can lead to unexpected problems from connecting all the grounds together. For example, your computer’s USB port can be a convenient source of 5 V, but the negative or ground side of that 5 V will likely be connected to the ground pin of the computer’s power cable and therefore to the ground side of everything else you have plugged into the wall. This can lead to unexpected problems as you build up your system, usually without thinking about your house being part of your circuit.

There are more and more solutions for effectively moving power and signals without having an electrical connection, so we will be working on adding those into our more integrated products, and we will be adding to our isolation module portfolio to support our customers with the building blocks to make safer and more reliable systems themselves.

The module we are introducing today can provide galvanically isolated and regulated 5 V or 3.3 V power at up to 200 mA. It’s based on the MIE1W0505BGLVH from MPS, and it’s amazing how much is integrated into a chip like that, including a transformer to get the power from one side to the other without an electrical connection. Only a few passives are needed to support the IC, allowing our board to be small (0.3″ × 0.6″) and low-cost. It’s easy to use, too, with all the necessary information provided on the product page. The datasheet is available if you want more information, but you can use this module without knowing the details in there. (This is unlike what we call “carrier boards”, which require you to familiarize yourself with the chip.)

We’re excited to announce the release of our new High-Power Stepper Motor Driver 36v8 for controlling large bipolar stepper motors. It operates over a wide 8 V to 50 V range and can deliver up to 8 A continuous per phase (11 A peak with sufficient additional cooling), making it our most powerful stepper motor driver by far. Here are some of its key features:

• Highly configurable through SPI interface
• Optional STEP/DIR control pins (stepping can also be controlled through SPI interface alone)
• Nine different step resolutions down to 256 microsteps: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, 1/128-step, and 1/256-step
• Adjustable current control lets you set the maximum current output, enabling the use of voltages above your stepper motor’s rated voltage to achieve higher step rates
• Adaptive blanking time, adjustable decay times, and various current decay modes enable the creation of ultra-smooth motion profiles through the SPI interface
• Optional STALL output enables stall detection when microstepping
• Optional BEMF output enables more advanced control and stall detection algorithms based on the back EMF of the stepper motor
• Driver supports alternate operating mode for controlling two brushed DC motors with PWM inputs instead of one bipolar stepper motor with STEP/DIR inputs
• Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
• Digital outputs are all open drain with pull-ups to externally supplied IOREF voltage for use with non-5V systems (IOREF can be connected to neighboring 5V OUT pin for use with 5V systems)
• Under-voltage lockout, over-current protection, short circuit protection, and reverse-voltage protection
• Arduino library and example sketches are available that provide basic functions for configuring and operating the driver

The 36v8 board has the same dimensions and pinout as the our older 36v4 version, so you can easily swap in this newer version to double the power to existing projects (or get the same power at lower temperatures).

We are pleased to announce that Pololu is now an authorized Dobot distributor, and our first offering from their catalog is a robot arm that we are especially excited about: the Dobot MG400 Desktop Cobot Robotic Arm. The Dobot MG400 is a departure from products typically available from Pololu. While the 8 kg (17 lb) unit is small for the collaborative robot world, it is much larger than typical Pololu products, and the cost is correspondingly higher as well. However, the price is still very competitive for what the robot arm offers, as the high ±0.05 mm positional repeatability, collision detection, and drag-to-teach ability make this cobot a compelling option for serious automation applications. With a footprint of 19 cm (7.5 in) square, the small size and low cost also make the Dobot MG400 accessible to many education and research applications that need more than a toy or hobby product. The following video shows off some of the arm’s features:

The Dobot MG400 has a maximum reach of 44 cm and can rotate through 320°, and it can lift payloads up to 500 g (18 oz). Dobot makes a sliding track module that substantially expands the operating envelope of this robot and a vision system, which are also available through Pololu (product pages for those are coming soon).

Please note that this arm does not include any grippers, but it does include a general-purpose flange for mounting end effectors that can be purchased separately from Dobot or other suppliers, or you can 3D print your own. A suction nozzle is included, but it requires an external air supply (compressor not included) to function.

The MG400 can be programmed a variety of ways, including through drag-to-teach positioning, a graphical programming interface, and Lua scripting. The controller in the base has plenty of I/O that makes it easy to integrate the robot into a bigger system.

The pictures below show example MG400 applications with custom 3D-printed electromagnet end effectors used to manipulate Micro Metal Gearmotors for packaging and testing.

We are excited to introduce our new series of stepper motor drivers based on the Allegro A5984 that offer an easy way to control bipolar stepper motors from supply voltages between 8 V and 40 V (absolute max). It’s hard to believe it’s been 15 years since we introduced the original A4983 stepper motor driver carrier in the small 16-pin form factor that would become ubiquitous for stepper motor drivers. We updated the product in 2011 when Allegro released the newer A4988, but since then we have released boards for stepper motor drivers from other semiconductor manufacturers, including Texas Instruments (most notably the DRV8825, and DRV8834, and more recently the DRV8434 series), Monolithic Power Systems (MP6500), STMicroelectronics (STSPIN820 and STSPIN220), and Toshiba (TB67S249FTG and TB67S279FTG). The new Allegro A5984 carriers, which can be used as drop-in replacements for the A4983/A4988 in many applications, bring us full circle with those original drivers, and with support from Allegro, we are able to offer them at extra low prices.

Minimal wiring diagram for connecting a microcontroller to an A5984 Stepper Motor Driver Carrier, Adjustable Current, Blue Edition.

As with our other stepper driver products, we are offering the A5984 carriers with small trimmer potentiometers for setting the current limit. However, these can be a little fiddly to work with, so we are also offering several fixed-current versions for cases where you just want a particular set point without having to tune each board (for volume applications, we can do custom production runs with whatever set point you need). We also have two PCB options—a standard 2-layer version that is most economical for lower-current applications, and a 4-layer “Blue Edition” for maximum performance that can deliver up to 1.2 A continuous per phase (heat sinks and active air flow can bump that higher). The following table shows all the options:

	Adjustable Current, Blue Edition	Adjustable Current	Fixed 1.5A@5V / 1A@3.3V, Blue Edition	Fixed 1A@5V / 660mA@3.3V, Blue Edition	Fixed 750mA@5V / 500mA@3.3V	Fixed 500A@5V / 330mA@3.3V

* This current exceeds what the module can deliver continuously and is only achievable for short durations or with sufficient additional cooling (e.g. adding heat sinks or active air flow).

Compared to those original A4988s, the A5984 carriers offer a number of improvements, including a higher maximum operating voltage, more microstep options and higher-resistance current sense resistors for improved microstepping performance, a fault output for reporting over-current faults, and an adaptive decay current control algorithm that automatically adjust the amount of fast decay to optimize the motor current waveform.

ACS71240 Current Sensor Carrier pinout.

We have released a ton of new current sensors! These boards, based on Allegro current-sensing ICs, have analog outputs with voltage proportional to the AC or DC current passing through the sensor while offering full electrical isolation of the current path from the sensor’s electronics. This isolation allows them to be inserted anywhere in the current path, including on the high side, and because the current path resistance is on the order of 1 mΩ or less, there is minimal effect on the rest of the system.

As with all our other carrier boards, we designed these current sensors to be usable in real-world applications rather than just as evaluation boards. To that end, we have released compact carriers for use in space-constrained systems and larger modules with more connection options available for higher-current applications. The large carriers offer better thermal dissipation thanks to their 6-layer PCBs and increased surface area, and the holes and slots for the current path connection points accommodate thicker wires along with a variety of high-current connectors (e.g. lugs, solderless ring terminals, and 4-pin terminal blocks).

We also want these modules to be usable as evaluation boards, so we have standardized our compact and large form factors, making it easier to swap among different boards to compare different sensor ICs. Additionally, having different form factors available for the same sensor IC makes it possible to evaluate how things like PCB area and the number of copper layers affects the sensor’s thermal performance.

Here is a quick summary of the four new sensor families:

• ACS71240: low-cost measurement of bidirectional currents ranging from 10 A to 50 A, with dedicated versions for 3.3 V and 5 V systems. A unidirectional 50 A, 5 V version is also available.
• ACS37220: low-cost measurement of bidirectional currents ranging from 100 A to 200 A, with dedicated versions for 3.3 V and 5 V systems. These have extra-low 0.1 mΩ current paths through the sensor IC and user-configurable overcurrent fault thresholds.
• ACS72981: high-bandwidth (250 kHz) measurement of unidirectional or bidirectional currents from 50 A to 200 A, with dedicated versions available for 3.3 V and 5 V systems.
• CT432/CT433: extra high-bandwidth (1 MHz), low response time (300 ns) measurement of unidirectional or bidirectional currents from 20 A to 70 A, with dedicated versions available for 3.3 V and 5 V systems. Unlike the other Allegro sensor families we carry, which use Hall effect sensing, the CT432/CT433 sensors use tunneling magnetoresistance (which Allegro calls XtremeSense™ TMR) and are optimized for high dV/dt applications.

More sensors are coming, and we will be releasing them as they become available. Do you have a favorite current sensor? Let us know in the comments!

We’re excited to introduce our new 60V-max H2 High-Power Motor Driver 36v11 CS, which joins our lineup of high-power motor drivers as the new highest-voltage option. Like our other high-power motor drivers, this board is a discrete MOSFET H-bridge that is designed to drive large brushed DC motors. The H2 36v11 can supply a motor with continuous currents up to 11 A over a wide 5 V to 60 V (absolute maximum) operating range. The board also features reverse-voltage protection and an on-board bidirectional current sensor that provides a direct measurement of the motor current.

The H2 driver is designed to be a near drop-in replacement for its predecessor and for our lower-voltage G2 drivers, with an identical form factor and a similar pinout. Compared to its predecessor, the H2 version adds improvements such as reverse-voltage protection, current sensing, and compatibility with 3.3V systems (as well as 5V). Compared to the newer G2 drivers, the main differentiator is the wider operating voltage range, but the H2 36v11 CS also adds an on-board bidrectional current sensor that provides a direct measurement of the motor current, even when the driver isn’t actively driving. There are also differences in the pinout, control interface, and some aspects of the operation, so please see the H2 product page for more information on compatibility between it, its prececessor, and the G2 versions.

Introductory special discount! To celebrate the release of the H2 36v11 CS, the first hundred customers to use coupon code H236V11CSINTRO can get up to three units for just $34.95 each!

We are pleased to announce the release of our new low-cost time-of-flight distance sensor featuring ST’s VL53L4CD. The VL53L4CD has a detection range of 1 mm to 120 cm (4 ft) with a resolution of 1 mm and an update rate of up to 100 Hz. This distance sensor is notable for being able to accurately measure the distances to objects even as they are almost touching the sensor face.

One interesting feature of the VL53L4CD is its Ultra-Low Power mode, which allows it to act as a basic proximity detector with greatly reduced average current consumption (less than 100 μA in some cases). In this mode, the sensor does not output distance and other data as usual; it simply raises an interrupt when a target is detected. This functionality is enabled with ST’s VL53L4CD ULP API (application programming interface), and the ULP and standard drivers can be used together to let the VL53L4CD switch from low-power proximity detection to accurate ranging once it sees a target. (ULP drivers are now available from ST for the VL53L1X and VL53L3CX as well.)

Introductory special discount!
