WiFi Module V1.0 ESP8266 - M10017 hwrev


The mRo WiFi radio is developed around the very popular ESP8266 module used in many IoT projects. The mRo WiFi module V1.0 comes with a standard JST-GH, allowing you to establish a UDP connection with your computer or mobile device and use mobile ground stations.

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.
