Note The main hardware documentation is here.

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.

编译固件

Tip大多数用户将不需要建立此固件! 它是预构建的, 并在连接适当的硬件时由 QGroundControl 自动安装。

为此目标 编译 PX4：

  1. 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.
