FrSky R9M Lite for Taranis X-Lite

FrSky introduced R9M Lite module designed especially for FrSky Taranis X-Lite transmitter. This transmitter module has unique small size (62.4mm × 30mm×14.5mm) and fits only on FrSky X-Lite transmitter. It would be great if this new form factor will become a new transmitter module size standart. R9M Lite is the Long Range System TX working in 915MHz/868MHz frequencies and providing 10km (and more) of control and telemetry range. R9M Lite module has two versions of the firmware: EU and non-EU. EU version provides up to 25mW of transmitting power and non-EU version – 100mW. This module is compatible and works with all of the R9 series receivers (R9S, R9Slim, R9 mini). 

Edit: One user (“KC” on RCG) has pinpointed a line in the OpenTX source indicating that there should be two power level settings for EU LBT firmware: 25mW with telemetry and 100mW without telemetry:
