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.

• Main System-on-Chip: STM32F427

  • CPU: 32bits, 168 MHz ARM Cortex^® M4 with FPU
  • RAM: 256 KB SRAM
  • 2MB Flash
  • ST Micro LSM303D 14 bit accelerometer/magnetometer
  • MEAS MS5611 气压计
  • InvenSense^® MPU6500 integrated 6-axis sensors

• Highlighted features:

  • CNC processed aluminum alloy case, light and solid
  • Built-in isolated IMU redundancy
  • Total 16 PWM output channel (8 main + 8 aux)
  • 1 extra I2C port for flow connection.
  • 1 extra USB port for companion computer connection (built-in UART-to-USB converter)
  • Exposed debug port for development

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.
