Happymodel CrossF4 ELRS AIO

Overview:

The Happymodel CrossF4 ELRS flight controller comes with integrated UART 2.4GHz ExpressLRS receiver and 5A Blheli_s 4in1 ESC which supports 1-2s. The board is ideally suited to Tinywhoops. The 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate and low latency, this flight controller is the one that all Race/Freestyle pilots needed. The built-in ELRS receiver is UART type (rather than SPI) which makes it faster and allows firmware upgrades just like the Happymodel EP1, via betaflight pass-through or WIFI. The default firmware is ELRS V3.0.1.
