Drone for BETAFPV F4 1S 5A AIO Brushless Flight Controller

The ultralight F4 1S 5A AIO Brushless Flight Controller is back available with new and upgraded features. Compared to the previous version, the new board uses Serial ExpressLRS 2.4G instead of SPI ELRS 2.4G, allowing it to support ExpressLRS V3.0 and also offering a Frsky RX version to choose from. The flight controller has been updated with a BMI270 gyro and BB51 ESC hardware. Additionally, this new board supports the Betaflight Blackbox function.

The flight controller is made of high-quality materials, with fewer burrs and a better texture, resulting in better wear resistance and a longer lifespan. The electronic components used in the construction are also of a higher quality, ensuring more stable electronic performance.

The flight controller comes with a Serial ExpressLRS 2.4G receiver, which can be updated via Wi-Fi or Betaflight serial passthrough. This makes it convenient for pilots to flash any version of ELRS RX firmware, especially the ExpressLRS V3.0, without the need to update the flight controller firmware.

For the Frsky version, the board reserves an SBUS port and a UART port, which are available for the SBUS protocol receiver or other external receivers. The flight controller also features an 8MB flash memory chip dedicated to Blackbox logging, providing an extremely powerful tool for tuning and troubleshooting an FPV drone.

The integrated motor pin connectors make it easy to install motors without soldering work. The particular design of the flight controller features an ultralight weight of only 3.6g (ELRS) or 3.7g (Frsky), excluding the power cable and BT2.0 connector. The reasonable layout and easy-to-build design, along with the 26*26mm mounting hole size, make it fully compatible with the whoop frame in the current market.

The flight controller's specifications include a STM32F411CEU6 (100MHZ) CPU, a BMI270 six-axis gyro, and a built-in Serial ExpressLRS 2.4G/SPI CC2500 (For Frsky) receiver with a line antenna. The firmware versions available are betaflight_4.3.1_BETAFPVF411 (ELRS) and betaflight_4.2.11_BETAFPVF411RX (For Frsky), both of which feature a built-in BetaFlight OSD.

The flight controller is compatible with various VTX options, such as the BETAFPV M03 350mW VTX or the TBS Unify VTX, which are recommended to be used with the flight controller. The power cable is 55mm long and comes with a BT2.0 connector.
