A high-power modular robotics and engineering platform, built around RP2040 and designed to drive the most ambitious robots, props and devices.

The Do-Everything Board 🦾

Yukon is a standalone controller that can be equipped with up to six interchangeable modules capable of driving high-powered hardware - this is made possible by the unique pin capabilities of Raspberry Pi's multitalented RP2040 chip. This flexibility means you can drive many unique combinations of motors, servos, steppers, speakers, LED strips and more, all from a single Yukon host!*

To ensure Yukon creations are adventure proof, each module is screwed down to ensure a solid mechanical and electrical connection.

Assembling Yukon 🚧

Big electronic projects can often involve a lot of soldering, splicing and other complicated assembly techniques, but not with Yukon! The host board and modules use solderless connectors wherever possible so it's fast and friction-free to get started, and simple to swap out components if you need to.

Powering Yukon ⚡

Supplying external power to Yukon is easy thanks to its chunky XT30 connector, which enables you to attach 2 to 4 cell Lithium Polymer (LiPo) batteries (or any other source from 5V to 17V) to deliver up to 15A continuous for your high-power projects.

An e-Fuse with switchable output is included to protect from accidental overvoltage and overcurrent events, along with internal sensors for monitoring voltage, current, and temperature whilst your programs run.

Programming Yukon 💾

Yukon is supported by a comprehensive MicroPython library with a whopping 50 (!) examples showing how to use the individual features of the board and all of its modules. There are also fully fledged showcase examples to show you how Yukon can be used to build a remote-controlled rover, spider tank, and pen plotter.

Yukon Make Anything! Kit Includes

You can buy a Yukon host (plus screws and feet) on its own, or as part of the fully-featured Yukon Make Anything! Kit, which sets you up with all the tools to make a bunch of cool stuff. It includes six different modules for driving a diverse range of hardware, plus a selection of useful cables for feeding your Yukon power and data.

• Yukon Host (plus screws and feet)
• Dual Motor / Bipolar Stepper Module
• Quad Servo [Regulated] Module 
• LED Strip Module
• Audio Amp Module
• Dual Switched Power Output Module
• Proto Module
• USB-A to USB-C cable for programming
• Loose wire to XT30 cable for power
• XT60 to XT30 cable for power
• ...all packed up neatly in a reusable Pirate-brand Loot Box.

Yukon Modules

Customise Yukon to suit almost any project with our range of addon modules. You can populate your Yukon with a full load-out right away, or start with a few modules and expand as your project grows. There's also a proto module, for if you want to add a custom module like a buzzer or a potentiometer.

Getting Started

You can find Yukon documentation, code examples and MicroPython builds at the link below:

• MicroPython firmware and library

If you'd like to program Yukon from an Android phone then you could try the DroidScript app, available on Google Play.  You'll need a USB-C cable and a recent version of MicroPython firmware installed on the board.

Connecting Breakouts

The Qw/ST connectors on Yukon make it super easy to connect up Qwiic or STEMMA QT breakouts. If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable.

Breakout Garden breakouts that don't have a Qw/ST connector can be connected using a JST-SH to JST-SH cable plus a Qw/ST to Breakout Garden adaptor. Want to use multiple Qw/ST breakouts at the same time? Try this adaptor!

Notes

• Measurements: 84mm x 67mm x 14mm (L x W x H). The mounting holes are M2.5 and 3mm in from each edge.
• Yukon has some extra broken out headers that adventurous makers might find useful (note that these are unpopulated and so will require soldering):
  • Control header for connecting up external on-off and user/boot buttons, as well as an external power LED
  • Expansion header for connecting up external A and B user buttons, an LCD display (or use as GPIO), and SWD debugging
• The board's current draw when off is 2.05mA @ 5V and 3.25mA @ 17V. As such it is recommended to disconnect any battery pack if the project is not going to be used for a while, to avoid unnecessary draining.
• Yukon comes with kapton tape on top of its 8 mounting posts. Remove these before installing any modules.
• * Some slot placement and combinations of modules may not be compatible due to shared pin functions

About RP2040

Raspberry Pi's RP2040 microcontroller is a dual core ARM Cortex M0+ running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.

One very exciting feature of RP2040 is the programmable IOs which allow you to execute custom programs that can manipulate GPIO pins and transfer data between peripherals - they can offload tasks that require high data transfer rates or precise timing that traditionally would have required a lot of heavy lifting from the CPU.
