A custom flight controller with IMU sensors for orientation, a GPS module, a Micro SD card slot, and support for my LoRa Transceiver module for telemetry along with a custom flight controller algorithm. I built this for my project of creating a custom drone from scratch..

To use plug in a 3 cell lipo battery into the XT60 connector and attach the ESCs to the 4 corner screw terminals. Then plug in the ESC headers into the coresponding ESC headers on the board. Make sure a GPS antenna is connected to the U.FL connector. Plug in my transceiver module into any of the UART headers. A Micro SD card is not strictly required but if inserted the board will log data and error logs.s.
