The Happymodel ELRS X2 AIO Flight Controller comes with an integrated SPI 2.4GHz ExpressLRS receiver and 12A Blheli_S ESC which supports 2-4S. Bigger Mosfet supports high to 12A currents and would be better for a 2-4S toothpick drone or long-range FPV drone. The 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate, and low latency. Featuring an MPU 6000 SPI sensor and OSD, this board is the perfect addition to your FPV build.
