# MindPX Hardware
|
|
|
|
:::warning
|
|
PX4 does not manufacture this (or any) autopilot.
|
|
Contact the [manufacturer](http://mindpx.net) for hardware support or compliance issues.
|
|

|
|
|
|
The AirMind<sup>®</sup> [MindPX](http://mindpx.net) series is a new generation autopilot system branched from Pixhawk<sup>®</sup>.
|
|
|
|
|
|
|
|
::: info
|
|
These flight controllers are [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).

|
## Quick Summary
|
|
|
|
::: info
|
|
The main hardware documentation is [here](http://mindpx.net/assets/accessories/Specification9.18_3_pdf.pdf).
|
|
:::
|
|
|
|
MindPX is a new generation autopilot system branched from Pixhawk<sup>®</sup>, 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<sup>®</sup> M4 with FPU
|
|
- RAM: 256 KB SRAM
|
|
- 2MB Flash
|
|
- ST Micro LSM303D 14 bit accelerometer/magnetometer
|
|
- MEAS MS5611 barometer
|
|
- InvenSense<sup>®</sup> 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<sup>®</sup> bi-direction telemetry D and S.Port.
|
|
|
|
For detailed Pin diagram, please refer to the [User Guide](http://mindpx.net/assets/accessories/UserGuide9.18_2_pdf.pdf).
|
|
|
|
### 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](../dev_setup/building_px4.md) 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.
