mRo Pixracer R15

PixRacer has all the capabilities of the original Pixhawk (including version 2) and even more! It is optimized in size and has just about the right amount of inputs/outputs that allow you to switch from a full-enriched autopilot stack system (with auto landing and full navigation) to a high-performance racing platform.

R15 has an updated accelerometer/gyro, magnetometer, and is ROHS (Lead Free). It also includes an ESP8266 for easy WiFi updates and comes with the latest Ardupilot ESP8266 firmwareopen in new window developed by Andrew Tridge. This new firmware has a nice web interface, MavLink2 support, and an easier way to do future updates via the web interface.
