The AR32FC is an H743-based flight controller for mission-critical drone applications, offering a 4–14S LiPo input range, integrated sensing and peripheral connectivity. Dual IMUs, a barometer and a three-axis magnetometer are incorporated into a compact 60 × 60 mm board, all built with non-Chinese-origin components.
A 5V servo and peripheral rail delivers up to 3A in aggregate, and a dedicated 12V video transmitter rail provides up to 3A continuously. The AR32FC features four servo outputs, six UART ports and two four-channel ESC JST-SH signal output connectors, together with USB-C and a microSD interface. Optional RJ45 Ethernet capability is available as an alternative to I2C, and two relay connections provide 12 V or VBAT feeds.
Custom firmware accommodates bidirectional DShot 150/300/600 and Servo PWM, with bidirectional DShot and KISS telemetry. The controller incorporates current limiting, overcurrent and temperature protection, low-voltage cutoff and signal-loss timeout. Additional transient protection uses snubbers and dual TVS devices.
