OpenIPC Mario AIO
OpenIPC Mario AIO is a compact module for a digital FPV system that combines a camera, a transmitter (VTX) and a system-on-chip (SoC). It is designed for use in drones and other FPV projects, providing high image quality and low video latency.

Power and connection
- Powered by a 2S–6S battery
- For low voltage (2S–3S) it is recommended to connect 4 power wires through a separate connector — more current is required.
- For 4S and above you can use the standard 2-wire connection.
- To lower the minimum supply voltage to ~5.4 V you can remove two resistors on the board.
UART pads and entering U-Boot
To enter U-Boot boot mode (debug mode) use the UART:
R0 / T0 — pads on the top of the board.
LED indicators
- Red blinking — battery power is on
- Red solid — Ethernet/USB connection
- Blue blinking — RF transmitter active
- Green — TBD (not implemented or changing)
Connecting to the flight controller
To connect the Mario AIO to a flight controller (e.g. SpeedyBee F405 WING) use the following connections:
- GND → GND on the controller
- VCC → VCC (check voltage compatibility)
- RX → TX on the controller
- TX → RX on the controller
⚠️ Before powering on, make sure all connections are correct.
