The name is a play on the fact that it's designed to be small and also runs on a Pi (Py) chip. Yes, that means you can program it with MicroPython (Py). The Pygmy was designed with the [Apache NuttX RTOS][nuttx] in mind (you can find the board support for it [here][pygmy-nx]), but it is also possible to program it using the Pico C SDK or MicroPython (or really, whatever else you can flash on an RP2040). Pygmy Rev B The prototype board Pygmy Rev B with its ground station sibling, PygmyGS. The flight computer also has a sibling ground station receiver, the PygmyGS. This board allows you to receive telemetry from the ground and can interface with consumer hardware like a laptop through its USB-C serial interface. The manufactured PygmyGS Rev A Handheld for scale The ECAD render of the PygmyGS Rev A Here is the Pygmy within my L1 rocket: Motivation I am a computer systems engineer who has designed avionics for my university's rocketry team for several years. I like the challenge of designing, building and programming embedded systems for unique environments, like the inside of a rocket. Although my L1 flight won't have the same challenges as my university's rockets (which fly up to 30k feet and have hit Mach 1.89), it will still have challenges unique to rocketry like high vibration and lots of different forces, arming requirements and logging speed requirements.
