The first signs of life of the flight controller I have been working on for a while now. Some specs PCB Length 78 mm PCB width 35 mm. Mass 17 g STM32F4 processor at 168 MHz STM32F4 processor PDF Can be powered from 3S to 5S lipo. Provides ample 5v output to power the Raspberry Pi nominally 2A. Video camera input and Vtx output with On Screen Display from the FC. The Input voltage is also fed out to the Vtx and cam so they dont need separate power lines Same hole spacing as a Raspberry Pi Zero, designed for a Raspberry Pi Zero companion to fit neatly. 4 uarts, 2 at 3v and 2 at 5v with optional signal invert I2C interface 2 port CAN interface PPM sum input, Analog RSSI input Bi-directional S.Bus as well as 6 independent optically isolated Servo/ESC outputs Ground is isolated between the flight controller and the RC outputs. The RC outputs can be powered from a UBEC or the ESC on small models. Several analog inputs for airspeed, Battery current and others. Dedicated battery voltage Onboard compass (LIS3MDL) and Baro (BMP280) and IMU ( BMI160) 1 Mbit EEprom uSD-Card slot From the top of the board The FC is designed for aeroplanes with slim fuselages so the connectors are orientated upwards or fore and aft. Typical installation would be under the main wing. From underneath From underneath with the Raspberry Pi Zero sitting about where it should be.
