EWRF E709MT3 – Stackable VTX with Betaflight OSD control

A new cheap stackable VTX, supporting Betaflight OSD control was listed – EWRF E709MT3 . Betaflight control means you can configure and change VTX channel/power via OSD. This VTX also supports PIT mode – when you need to power up the quad with VTX set to OFF. Another features are protection from powering without antenna, thermal protection from overheating, supporting 2S-6S power input and 5V 800mA output.

Really cool feature set for such a price.
