Product overview
The Hongfei APO22MINI is a flight-control component for formation and terminal tracking UAV integration. Its STM32H743 processor works with two sets of ICM-42688-P accelerometers and gyroscopes, plus two MS5611 barometers. The redundant sensor architecture supports automatic data-source switching after partial sensor failure. Double-sided shielding provides protection against external interference and impurity ingress. At 43mm*43mm*11.3mm and 22g, the controller has a compact physical envelope for installation, with GH1.0 plug connections linking it to other aircraft equipment.
Integration options include 12 PWM control channels, seven extended serial ports, one CAN channel, two I2C channels and one S.Bus channel. The controller supports an external compass; the MS4525DO airspeed module is optional. Power input must remain within DC14.8-50V, while voltage monitoring covers 12.6-50V. Ground station functions cover monitoring, alarms, remote control and route planning. Formation operation supports up to 30 aircraft without requiring an onboard computer. Operating temperature is -20ºC~85ºC, with storage specified at -40ºC~85ºC.
