The GL658 radio transmitter contains all vital elements on one board. The board is responsible of reading state of control sticks and switches, doing proper ADC conversion, then transmitting the control signal. But it also receives the Lightbridge video signal and telemetry from the drone, transcodes it and provides USB interface for reading the data and reconfiguring the drone from a mobile device.
There are 3 variants of GL658 controller used in Inspire products. Very similar boards are also used in GL300 remote controllers.
