Big Motor + Encoder Module for Yukon

by Pimoroni

Drive a powerful brushed motor (with encoder feedback) at up to 8A continuous from your Pimoroni Yukon project.

Featuring a gate driver with dedicated H-bridge FETs, this module can deliver a surprising amount of power for its size across Yukon's 5 to 17V input voltage range. There is a landing for a header to connect up encoder feedback from your motor. This is left intentionally unpopulated, giving you the choice of 0.1" connector to use.

We used two of these modules (one for each side) and a chunky Dagu Wild Thumper Chassis to build our rugged remote controlled rover!

Motors are sold separately.

Features

  • DRV8706H smart gate driver (datasheet) with external h-bridge FETs (datasheet)
  • Drive one brushed DC motor with encoder feedback
  • 5mm spaced screw terminals for attaching your motor
  • 8A continuous current (12A peak)
  • Current, temperature and fault sensors
  • Fully-assembled
  • Soldering required for use of the encoder
  • Compatible with Pimoroni Yukon

Software

As well as the usual examples we've also added the full code for our remote-controlled rover as one of our showcase examples, to show you what a complete project involving Big Motors might look like.

Pinout and Schematic

Notes

  • Measurements: 24mm x 20mm x 15.3mm (L x W x H).
  • This module uses either the RP2040's PWM hardware or PIO to control the motor output, depending on the code used. With PWM, only four modules can be used simultaneously (for a total of 4 dc motors), and they should be placed in Yukon Slots that do not share the same PWMs. PIO does not have this restriction letting all six slots be used (for a total of 6 dc motors), at the cost of using up a PIO state machine.
    • PWM 1A/1B are on Yukon Slots 1 and 5
    • PWM 3A/3B are on Yukon Slots 2 and 6
    • PWM 5A/5B are on Yukon Slot 3 (5A/5B are also on GP26/GP27)
    • PWM 7A/7B are on Yukon Slot 4
  • Each encoder uses a PIO state machine, for a total of six across all Yukon Slots.

About Yukon

Yukon is a high-power modular robotics and engineering platform, built around Raspberry Pi's formidable RP2040 chip. It has slots for attaching interchangeable hardware modules for driving combinations of devices such as motors, servos, steppers, and LED strips, all from one board!

Featuring an XT30 connector, Yukon can be directly powered off 2 to 4 cell LiPo batteries (or any other 5 to 17V source), to deliver up to 15A continuous for your high-power projects. An e-Fuse with switchable output protects the board, along with voltage, current, and temperature sensors that can be monitored by your programs.

Simply the best and most powerful MCU on the hobbiest market at the moment. Even the arduino setup works out of the box. So far I've tested I2C, SPI, Audio, USB audio, Rotary Encoder and SDIO card libs - all work flawlessly and fantastically well. Running some audio spectrum processing the Arm CMSIS libs for a 4096 FFT takes around 412us (0.4ms) including mag squared calcultions and all the various buffer copies - amazing stuff!

As someone dealing with microcontrollers for the first time the teensy is excellent. Incredible performance for the size and while it doesn't have a massive community the examples that are part of the ide are really detailed.

Got one as soon as they were back in stock. Arrived quickly and well packaged. Couldn’t be happier with this amazing board/service!

Nice little board with quite a bit of juice and a lot of connection options. Really nice that you can use it as a USB host, and that it has pinouts for ethernet too. Haven't tested all the stuff it can do, as I mainly use mine to run a DirtyWave M8 tracker/synth.

Fast delivery & well packaged. Using the Teensy 4.1 to run the "headless" version of the M8 tracking software - works great and setup was way easier than I expected.

I have soldered on the pins, and its running on my breadboard. I probably have not yet accessed 1 per cent of what this fantastic little board can do... I'm using Visual Studio Code with PlatformIO, all seems good so far....

Absolutely wonderful card. Incredibly fast and stable. Lots of RAM and lots of flash memory. It is also possible to expand both RAM and flash by soldering circuits on the underside of the card. With good code examples and a content-rich forum. Works well to write code in both Arduino and Visual Studio. I really love this circuit

This is a high end microcontroller. The USB host interface works very well with some good examples in the library. You can solder two PSram chips on the bottom for a Whopping 16GB of ram!!

So far the board works and powers on. I'm yet to use other features on it but Very excited. Order was quick and will use this website more often
