Compared to the previous version, the new board uses Serial ExpressLRS 2.4G instead of SPI ELRS 2.4G so that it can support ExpressLRS V3.0 and also has a Frsky RX version to choose from. We updated the FC with high-quality BMI270 gyro and BB51 ESC hardware. In addition, this new board supports the Betaflight Blackbox function.   *** IMPORTANT *** REVIEW LINK *** BETAFPV *** ANNOUNCEMENT ***  https://betafpv.com/collections/brushless-flight-controller/products/f4-1s-5a-aio-brushless-flight-controller-elrs-2-4g   Betaflight Firmware and CLI F4 1S 5A AIO Brushless Flight Controller comes with the default firmware betaflight_4.3.1_BETAFPVF411 (ELRS) or betaflight_4.2.11_BETAFPVF411RX (Frsky). The default firmware for Serial ExpressLRS 2.4G RX version supports ELRS V2.4 RX. Pay attention, For the Serial ExpressLRS 2.4G version, ONLY the newest Betaflight firmware 4.3.1 start to support this BMI270 gyro. For the SPI Frsky version, 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.

For example, the theoretical failsafe RSSI values for 250Hz packet rate are -108dBm. Actually, the RX will be possibly lost in control when the RX RSSI values reach about -92dBm.   Package 1 * F4 1S 5A AIO Brushless Flight Controller (ELRS or Frsky) 4 * M1.2x4mm Screws 4 * M1.4x5mm Screws 4 * Anti-vibration Rubber Dampers 8 * Motor Pin Connectors (Light version included) Flight Controller Warranty Policy At weBLEEDfpv, we are committed to providing high-quality products.
