Ep.05 - S1|E5: From Zero to Flight-Ready - Drone Telemetry with CircuitPython

This week on Build, Create & Learn – A Maker’s Journey, I finally put the Adafruit Feather RP2040 and CircuitPython to the test — and the results were a huge step forward for my drone telemetry project.
After weeks of SD card frustration on STM32, I’m relieved to say: the new setup just works. From a simple blinky app to logging environmental data and GPS coordinates straight to a microSD card, I now have the first version of a working telemetry logger. And with my mechanical engineering hat back on, I’ve also started sketching and 3D printing ideas for the enclosure that will carry it into a real drone flight.
What you’ll hear in this episode:
- Setting up the Adafruit Feather RP2040 with CircuitPython
- Running the first “blinky” and rainbow LED examples
- Reading environmental data with the BME280 sensor
- Finally getting reliable SD card logging with sdcardio
- Adding GPS data to the logger with Adafruit’s GPS library
- Why I chose not to solder everything down yet — a maker’s choice
- Starting the design process for a flight-ready enclosure
It’s the most complete version of the telemetry system so far, and it feels amazing to see the pieces finally coming together.
