The ultralight F4 1S 5A AIO Brushless Flight Controller is back in stock with new and upgraded features. 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.
