RoboClaw 2x60A Motor Controller (V6)

Posted by Ryan on 18 April 2017
Tags: new products

The RoboClaw 2x60A motor controller (V5) we’ve been carrying has been replaced by the new RoboClaw 2x60A Motor Controller (V6). This powerful motor controller can drive two brushed DC motors with 60 A continuously at voltages from 6 V to 34 V, and it allows for peak currents up to 120 A. Version six adds a protective aluminum plate to the board bottom and ports for connecting optional cooling fans that are controlled based on the board temperature.

The RoboClaw motor controllers from Ion Motion Control can control a pair of brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system, or analog feedback can be used for position control.

Wall Power Adapter: 5.25VDC, 2.4A, 20AWG MicroUSB Cable

We’ve added this Micro-USB wall adapter to our catalog. It can supply up to 2.4 A at 5.25 VDC (the USB specification’s maximum bus voltage), allowing for voltage drop due to power draw when powering 5 V electronics. It features a 1.5 m to 1.8 m (5 ft to 6 ft) DC power cord with 20 AWG wires that is terminated by a USB Micro-B connector, which makes it great for powering devices like a Raspberry Pi (especially newer Raspberry Pi models, like the Pi 3, which can draw a lot of current!).

Verbal Machines VM-CLAP1 Hand Clap Sensor

Don’t hold your applause: we are now offering the Verbal Machines VM-CLAP1 Hand Clap Sensor! This board is a low-power, microprocessor-based audio sensor that can detect hand claps or finger snaps while ignoring background noises such as human speech or music. It operates from 2.5 V to 5.5 V and offers a simple interface: when a clap or snap is detected, the output pin goes low for 40 ms, and the integrated blue LED lights up.

FEETECH High-Torque Servo FS5115M

We added the FEETECH High-Torque Servo FS5115M to our expanding RC servo selection. This standard-size analog servo has a stall torque of 215 oz-in (15.5 kg-cm) at 6 V, more than twice the torque of our standard-size servos with plastic gears thanks to its powerful motor and all-metal gear train. This higher torque requires more power: this servo can draw bursts of current in excess of 3 A at 6 V, about three times higher than a typical standard-size servo. The output shaft is supported by two ball bearings for reduced friction.

Comparison to the Power HD 1501MG high-torque servo

This servo is a lower-cost alternative to the 1501MG from Power HD, which has nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5115M and the 1501MG side by side:

FEETECH Ultra-High-Torque, High-Voltage Digital Giant Servo FT5335M

We added the FEETECH Ultra-High-Torque, High-Voltage Digital Giant Servo FT5335M to our expanding RC servo selection. This giant-scale digital servo can deliver twice the torque of our strongest standard-size servo, offering up to 550 oz-in at 7.4V or 480 oz-in at 6 V. This torque requires significant power: the FT5335M can draw bursts of current over 9 A at 7.4 V, and unlike typical hobby servos, has an operating voltage range of 6 V to 7.4 V.

The FEETECH Ultra-High-Torque, High-Voltage Digital Giant Servo FT5335M has an all-metal gear train.

This servo is a lower-cost alternative to the very similar 1235MG from Power HD. The two servos are approximately the same size, though the mounting hole spacing differs between the two, and they have almost identical performance specifications. The output shaft of the 1235MG is supported by two ball bearings while the output shaft of the FT5335M is supported by bushings. The picture below shows both the FT5335M and the 1235MG side-by-side:

Aluminum standoff for Raspberry Pi

Posted by Ryan on 29 March 2017
Tags: new products

We are now carrying the Aluminum Standoff for Raspberry Pi: 11mm Length, 4mm M2.5 Thread, M-F. The 11 mm body length is just right for mounting expansion PCBs or HATs with standard-size female headers on a Raspberry Pi. The male M2.5 threads extend another 4 mm past the standoff body, and the female M2.5 threads extend at least 6.35 mm into the body. We carry M2.5 nuts and 6 mm M2.5 screws separately.

Two of these standoffs are needed to mount a Raspberry Pi on a Balboa 32U4 robot:

We also carry a 11 mm standoff with longer, 6mm threads. (We do not recommend these for the Balboa because the threads hit the robot chassis.)

New 5V step-up/step-down voltage regulator S9V11F5

Tags: new products

Our newest step-up/step-down voltage regulator, the S9V11F5, takes input voltages between 2 V and 16 V and increases or decreases that voltage as necessary to produce a fixed 5 V output with a typical efficiency of over 90%. (Note that it requires a minimum of 3 V to start up, but it can operate down to 2 V once it is running.) It can temporarily deliver peaks of around 2 A, and the maximum continuous output current depends on the input voltage as shown in the graph below:

The ability to raise or lower the input voltage makes this regulator especially well suited for battery-powered applications where the nominal battery voltage is close 5 V, such as when using four NiMH cells, since the battery voltage transitions from above 5V to below as the battery discharges. The wide input voltage range is also great for applications where you want a lot of flexibility in power supply choice or for systems powered by alternative energy sources like solar or wind, where the output voltage can vary a lot.

With a wider input voltage range and its ability to deliver more current, the S9V11F5 is a higher-performance alternative to our popular S7V7F5 buck-boost regulator, all while being even smaller in size thanks to its double-sided assembly.

For more information on this regulator, visit the S9V11F5 product page, and for other regulator options, you can take a look at our full selection of step-up/step-down regulators, step-up voltage regulators, and step-down voltage regulators.

New M3 screw lengths

Tags: new products

We added some new M3 screw lengths to our catalog: 6 mm, 10 mm, 12 mm, 14 mm, 16 mm, and 20 mm. (We already had 5 mm, 8 mm, 25 mm screws, and M3 nuts.) Along with the general usefulness of a large selection of hardware, this greater variety of available lengths will help make it easier to mount accessories to your new Balboa 32U4 balancing robot’s M3-compatible mounting points.
