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.
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 barometer
- 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

# 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.
# 编译固件
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.
