mRo Pixracer R15
Background/History of the product:
PixRacer has all the capabilities of the original PixHawk -including version 2- and even more! But is optimized in size and has just about the right amount of input/outputs that allows 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). Includes an ESP8266 for easy WiFi Updates. Comes with the latest Ardupilot ESP8266 firmware 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.
