Bench Power Module for Yukon (5A Step-down DAC)

by Pimoroni

Output a variable voltage of up to 12V from your Pimoroni Yukon project, with this 5A step-down regulator. You can adjust the output voltage programmatically and in real-time!

Use this to power devices that accept a variable voltage such as PC fans, and single colour LED strips. Alternatively, there is a "lock" trace on the underside that can be cut to fix the output at 5V regardless of the signal it is being given. In addition, there are two unpopulated digital IO signals exposed (with neighbouring 3.3V and GND pads) that can be used to connect up digital sensors to use as feedback.

Features

  • TPS54A24 step-down converter (datasheet)
  • Adjustable 3V to 12V output*
  • 5mm spaced screw terminals for attaching your output
  • 5A continuous current (10A peak)
  • 5V "lock" mode via cuttable trace
  • Exposed digital IO pads for feedback
  • Voltage, temperature and power good sensors
  • Fully-assembled
  • Soldering required for use of digital IO
  • Compatible with Pimoroni Yukon

Pinout and Schematic

Notes

  • Measurements: 24mm x 20mm x 15.3mm (L x W x H).
  • * To achieve the module's full output voltage range, Yukon's input voltage needs to at least 12V. For input voltages below 12V the module will only deliver up to that voltage on its output.
  • This module uses the RP2040's PWM hardware to control the output voltage. This means that only four modules can be used simultaneously, and they should be placed in Yukon Slots that do not share the same PWMs.
    • PWM 0B is on Yukon Slots 1 and 5
    • PWM 2B is on Yukon Slots 2 and 6
    • PWM 4B is on Yukon Slot 3
    • PWM 6B is on Yukon Slot 4

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
