File 02 · Flight Controller
A flight controller, minus what you don’t need.
An RP2354 dual-core M33 running Betaflight on a 6-layer board: a 6-axis IMU, microSD blackbox, PIO-driven analog OSD (in development), and a switchable 10 V VTX rail. No barometer, no onboard radio. Bring your own RX over UART and keep the board small and cheap.
