MindPX Hardware
The MindPX series were created by AirMind®. Please refer to: http://mindpx.net
Quick Summary
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 makes 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.

How to build
Please follow Getting Started and Building the Code. The target for MindPX is nuttx_mindpx-v2_default:
make nuttx_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.
