It is Arduino based converter for processing Mavlink telemetry data and send them in Duplex format (Ex but also old text one) into your receiver (and down to earth)

Features :

- sending data over Ex protocol

- sending data as text to even old Jetiboxes (include messages)

- Alarms

Here is wiring, it is really simple :   Code using one hardware serial for reading telemetry from Mavlink board (ArduCopter or MegaPirateNG) and output data into Jeti as software serial.   Here is video to show Alarms https://www.youtube.com/watch?v=bKOuzuYNKlU
