Note These flight controllers are manufacturer supported.

# Quick Summary

Note The main hardware documentation is here (opens new window).

MindPX is a new generation autopilot system branched from Pixhawk®, been revised in schematic and structure, and been further enhanced with new features to make un-manned vehicle more smart and more friendly to use.

MindPX increases total PWM output channels to 16 (8 main outputs + 8 aux outputs). This means that MindPX can support more complicated VTOL configurations and more fine control. It is especially meaningful for those FMU-V4 based flight controllers as MindPX implements main and aux output in one single FMU.

# Radio Receiver

MindPX supports a wide variety of radio receivers (since V2.6) including: PPM/SBUS/DSM/DSM2/DSMX. MindPX also support FrSky® bi-direction telemetry D and S.Port.

For detailed Pin diagram, please refer to the User Guide (opens new window).

# Building Firmware

TIP

Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.

To build PX4 for this target:

make airmind_mindpx-v2_default

# Companion PC connection

MindPX has a USB-TO-UART Bridge IC on the board. A micro-USB to USB type A cable is used for the connection. Connect micro-USB end to the 'OBC' port of MindPX and USB type A end to companion computer.

And the max BAUD rate is the same with px4 family, which is up to 921600.
