BetaFPV F4 1S 12A Brushless Flight Controller| SPI ELRS 2.4G V2.2

F4 1S 12A AIO Brushless Flight Controller V2.2 is the default flight controller for the Cetus X brushless quadcopter, which also works great for 85mm drones like Meteor85 and 3-inch toothpick drones like HX115 SE Toox. We have updated FC to version 2.2 with BMI270 gyro and BB51 ESC hardware instead of ICM20689 gyro and BB21 ESC hardware.
