The BrainFPV RE1 (Racing Edition 1) flight controller integrates an F4 based chip with a built-in OSD. Features high quality accelerometer & gyroscope sensors. This controller is built with racing in mind: a two direction, programmable race transponder is on-board. The transponder is programmable through the OSD and supports both iLap and Trackmate.
The RE1 is designed to be easily stack able with the mPB PDB.
