@Robert-Me2 Robert-Me2 changed the title i2c Bus of Mamba F405 Mk2 30mm FC Support. This FC has SCL and SDA terminals but I am not able to activate the compass of BN-880 and/or Baro of bpe/bpm-280 (4 terminal, 5v version) to this flight controller using INAV. The target used was FURYF4OSD (recommended by Diatone; is there an alternative target?) using INAV v2.6. The wiring was checked many times, no shorts. I tried each device individually then both together, varied bus speeds from 100-800 in INAV config. My last test was to add one 4.7k pull up resistor to compass and baro without success. After all my efforts I questioned if i2c bus is actually supported on this board becuase the updated version of this FC (the Mk3 30mm F405, available 21-Jan-2021) states that it now has functional i2c Bus. Please comment if you have experience with this FC using INAV gps, compas and baro. What should I try next? Thank you all for your efforts! i2c Bus of Mamba F405 Mk2 30mm FC Support. FlySky iBus receiver is on UART3, GPS on UART6.
