MicoAir743 User Manual
Overview
This document summarizes the MicoAir743 power, communication, sensor, and actuator interfaces for wiring checks, system integration, and troubleshooting.
Verify supply voltage ranges and connector orientation before wiring to avoid damaging the flight controller or peripherals.
Core Interfaces
| Interface | Purpose | Notes |
|---|---|---|
| USB-C | Firmware updates, debugging, and parameter setup | Use a USB cable that supports data |
| UART | MAVLink, GPS, telemetry, and serial peripherals | Cross TX and RX |
| I2C | Compass, airspeed, and expansion sensors | Verify peripheral voltage and address |
| PWM | ESCs, servos, and other actuators | Check output channel mapping |
Power and Wiring Safety
- Check supply polarity and voltage with a multimeter before power-up.
- Do not hot-plug peripherals that do not support it.
- Telemetry, GPS, and sensors must share ground with the flight controller.
- Use a current-limited supply when connecting high-power actuators for the first time.
Example Configuration
TELEM1: MAVLink2 / 115200 baud
GPS1: GPS / Auto baud
I2C1: Compass and airspeed sensor
PWM1-4: Motor outputs
