We’ve just released our VL53L0X Time-of-Flight Distance Sensor Carrier. With its ability to measure distances up to 2 m depending on configuration, target, and environment, the VL53L0X is a longer-range version of the VL6180X (but without ambient light sensing functionality) that operates using the same principles. This integrated lidar module times how long it takes for pulses of infrared light to reach a target, reflect off it, and arrive back at the sensor. It uses this information to report the range to the target with a resolution of 1 mm and accuracy as good as ±3%, minimizing the effect of the target’s reflectance on the measured distance.

As usual, our breakout board adds a 2.8 V regulator and level shifters to help interface with 3.3 V and 5 V systems, as well as a breadboard-compatible pinout and mounting holes. We are also working on an Arduino library for the VL53L0X that we expect to release in the next few days.
For more information about the VL53L0X carrier, see its product page.
We are now offering the Hakko FA-400 Smoke Absorber. The Hakko FA-400 is a benchtop smoke absorber for removing smoke generated by soldering. It has an easily-replaceable activated-carbon filter and a sturdy ESD-safe housing that can be oriented horizontally or vertically.
We’ve updated our USB Micro-B Connector Breakout Board with some minor improvements that should make it a little nicer to work with.
On the original version, the mounting cutouts didn’t work as well as we wanted: they were shallow, and the board was often prone to slipping out of place between two screws. The new version is wider and its cutouts are deeper to allow for more secure mounting, and it is slightly shorter in the other direction (0.4″ × 0.6″ with the connector).
For more information, see the board’s product page.
Our micro metal gearmotors are now available in 12 V versions! These high-power motors have long-life carbon brushes (HPCB) and offer the same performance as the 6 V HPCB motors at their respective nominal voltages; the only difference is that the 12 V motor draws half the current at twice the voltage.
The new 12 V gearmotors are available across our usual range of 11 gear ratios and in single- and dual-shaft versions. Along with our existing selection of micro metal gearmotors, this brings the total number of unique options available to 107:

We are now offering the Raspberry Pi 3 Model B. The Raspberry Pi is a popular credit card-sized computer that can run ARM Linux distributions. As the successor to the Raspberry Pi 2 Model B, the Pi 3 has a more powerful processor and adds wireless connectivity. Here are the specific improvements:
- 1.2 GHz 64-bit quad-core ARMv8 CPU
- 802.11n Wireless LAN
- Bluetooth 4.1
- Bluetooth Low Energy (BLE)
Along with these improvements, the Raspberry Pi 3 maintains compatibility with and the form factor of the previous Pi 2 (and Pi 1 Model B+). With its 0.1″-spaced GPIO header and small size, the Raspberry Pi also works as a programmable controller in a wide variety of robotics and electronics applications. It can also be combined with our A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge to make a great controller for a small robot. We also carry a selection of Raspberry Pi expansion boards.

We just added 16 new micro metal gearmotors to our already huge selection, including three totally new MP (medium power) gear ratios: 5:1 MP, 210:1 MP, and 250:1 MP. With these new additions, we now have dual-shaft versions available in any combination of our 11 gear ratios and four motor types, giving you 44 different options that work with encoders like our magnetic encoder pair kit.

In all, this increases our total selection of micro metal gearmotors to 85 unique options:
We’ve updated our Wixel Shield for Arduino with a few minor improvements. The Wixel Shield provides an easy way to connect a Wixel wireless module to your Arduino or A-Star 32U4 Prime, enabling wireless communication and even wireless programming (on some Arduinos). However, the original version of the shield was released many years ago, so it was not designed with the modern pinout of the Arduino Uno R3 in mind.
The Wixel Shield v1.1 adds pass-throughs for the four new pins—SCL, SDA, IOREF, and an unused pin—introduced by the R3 and present on all newer Arduinos, making it easier to stack other shields with it (especially ones that make use of the new I²C pin location). It also features improved level shifter circuits that make use of the IOREF voltage provided by the Arduino, allowing the shield to work automatically with both 5 V and 3.3 V Arduino boards.
The Wixel Shield for Arduino v1.1 is available by itself and as part of a combination deal that includes a pair of Wixels and a USB cable. See the user’s guide for the shield for additional information.
The updated MP3 Trigger V24 from SparkFun is now for sale. This new version features improved firmware that can read a configuration file from the SD card, making it much easier to use without a microcontroller. We posted previously about a project using an A-Star 32U4 and an MP3 Trigger to make a Scary shaking tombstone. The MP3 trigger also pairs nicely with the Maestro Servo Controllers because you can use a Maestro servo controller’s scripting capability to trigger sounds to play in sync with motion. You can see examples of how people are using them on our forum here and here.
I’d like to introduce our latest addition to the Pololu stepper motor driver carrier family, the DRV8880 Stepper Motor Driver Carrier. This carrier for the Texas Instruments DRV8880 driver has the same form factor and basic layout as our A4988 carrier, which makes it a drop-in replacement in many systems. It also has a lot of the same features, like potentiometer adjustable current control and microstepping down to 1/16-step. In addition, the DRV8880 has many new features like inputs for dynamically scaling the current limit to 25%, 50%, 75%, or 100% of the limit set by the potentiometer, nine decay mode combinations, and autotune (insert Daft Punk joke here), which automatically selects the decay mode each PWM cycle for optimal current regulation performance.
The DRV8880 carrier has a maximum current of 1.6 A, and in our tests it could handle about 1 A per phase continuously. It has a 6.5 V to 45 V input voltage range, which is the widest of any of our stepper motor drivers, and it supports both 3.3 V and 5 V logic. For more information about our DRV8880 stepper motor driver carrier, please see its product page.
We’re excited to offer a series of APA102C-based addressable RGB LED panels, which make it easy to add colorful images, text, or lighting effects to your project. These panels use the same integrated APA102C LED driver as our APA102C-based addressable RGB LED strips, which means that you can control the LEDs using a standard SPI interface that works over a wide range of communication rates.
We offer APA102C LED panels in three different sizes:
