# MindRacer Hardware


PX4 does not manufacture this (or any) autopilot. Contact the manufacturer (opens new window) for hardware support or compliance issues.

The AirMind® MindRacer (opens new window) series is a fully stackable flight platform for miniature UAVs. The platform currently has two RTF vehicles: MindRacer 210 and NanoMind 110.



This flight controller is manufacturer supported.

# Quick Summary

MindRacer is a fully stackable flight platform for miniature UAVs. Based on MindPX, MindRacer further scales down in formfactor while focused on providing modularity. MindRacer is a platform rather than a flight controller.

MindRacer implements the SEP (soldering-elimination-port) and WEP (wiring-elimination-protocol) concepts. Before SEP and WEP, soldering and wiring are always the major pain and efficiency killer during UAV manufacturing and tuning.

# How to Build


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

MindRacer has an attached Adapt IO board.

Attached Adapt IO board

MindRacer has a built-in UART-to-USB converter. To connect a companion computer, stack MindRacer on an interface board, and connect the companion computer to the USB port on the interface board.

And the max BAUD rate is the same with px4 family, which is up to 921600.
