BETAFPV F4 1S 5A AIO Brushless Flight Controller with Built-in SPI Frsky Receiver, 8MB BlackBox, BT2.0 Cable Connector for 65/75mm 1S Micro FPV Whoop Drones

Notice: The BLHeli_S firmware could support the BB51 hardware now. This board is powered by BB51 hardware. If you want to setup the ESC specification, please use the BLHeliSuite16714902A_Beta or ESC-Configurator. BetaFlight Configurator, BLHeli Configurator, and Bluejay Configurator are invalid for the BB51 ESC now. SPI Frsky version does not support motor direction set through Betaflight Configurator. The default protocol is configured to Frsky D16 FCC out of the factory. Pilots could set up the protocol according to your own need in Betaflight Configurator. DO NOT flash the other firmware, otherwise, the RX will be lost in control at a very close range. We have already built our own firmware betaflight_4.2.11_BETAFPVF411RX for SPI Frsky RX version to support BMI270 gyro.
