BETAFPV F4 1S 5A AIO Brushless Flight Controller for 65/75mm 1S Micro FPV Whoop Drones

The BLHeli_S firmware now supports the BB51 hardware. This board is powered by BB51 hardware. If you want to set up the ESC specification, please use the BLHeliSuite16714902A_Beta or ESC-Configurator. BetaFlight Configurator, BLHeli Configurator, and Bluejay Configurator are no longer valid for the BB51 ESC. The SPI Frsky version does not support motor direction set through the Betaflight Configurator. The default protocol is configured to Frsky D16 FCC out of the factory. Pilots can set up the protocol according to their own needs in the Betaflight Configurator. DO NOT flash any other firmware, otherwise, the RX will be lost in control at a very close range.

We have already built our own betaflight_4.2.11_BETAFPVF411RX firmware for the SPI Frsky RX version to support the BMI270 gyro. The FC CPU specification is STM32F411CEU6 (100MHZ) with a Six-Axis: BMI270 and a built-in SPI CC2500 (Frsky) Receiver. The receiver antenna is a line antenna, and the FC size is 3030mm with a 2626mm mounting hole size. The firmware version is betaflight_4.2.11_BETAFPVF411RX, and it has a built-in BetaFlight OSD and an 8MB Blackbox.

We recommend using a VTX with a power of 200mW or more, such as the BETAFPV M03 VTX or the TBS Unify VTX. The power cable is 55mm long with a BT2.0 connector, and the weight is 3.7g, excluding the power cable and BT2.0 connector.

The ESC specification includes a 1S power supply, 5A continuous current, and a peak of 6A (3 seconds). The ESC firmware is A_X_5_.HEX for the BB51 BLHeli_S hardware, and it supports D-shot150, D-shot300, D-shot600, Oneshot125, Multishot, and PWM.

The package includes 1 * F4 1S 5A AIO Brushless Flight Controller-Frsky, 4 * M1.2x4mm Screws, 4 * M1.4x5mm Screws, and 4 * Anti-vibration Rubber Dampers. The BETAFPV F4 1S 5A flight controller comes with a built-in SPI Frsky receiver (CC2500 chip), which is compatible with Futaba S-FHSS, Frsky D8, and D16 protocols. It also has an SBUS port and a UART port, which are available for the SBUS protocol receiver or other external receivers.

BETAFPV has updated the FC with a high-quality BMI270 gyro and BB51 ESC hardware. If you want to set up the ESC specification, please use the BLHeliSuite16714902A_Beta or ESC-Configurator.

The FC has an 8MB flash memory chip dedicated to Blackbox logging, which is an extremely powerful tool for tuning and troubleshooting an FPV drone.

The F4 1S 5A AIO FC adopts a classic cross-shape design with an ultralight weight of only 3.6g, a reasonable layout, and easy to build. With a 26*26mm mounting hole size, it is fully compatible with the whoop frame in the current market, making it particularly suitable for weight-sensitive 65/75mm wheelbase micro whoop drones.
