Die Meldung kam vom EdgeTX Team, von RadioMaster wird man vorerst durch Chinese New Year nix hören.
Hier der Post aus dem EdgeTX Discord:
Important information for RadioMaster Ranger Micro and Nano ExpressLRS module users: The EdgeTX team has been informed by several users of a potential problem with these modules when powered via the XT30 connection. Especially when using a dedicated battery to power these modules, there is a high chance that you will overload and damage (burn-out) the external bay power circuit on your radio and/or module. Since RadioMaster is currently offline due to the Chinese New Year holiday, we HIGHLY recommend that users DO NOT externally power these modules until there is an official response from RadioMaster. This issue only affects the Ranger Micro and Nano modules. The BIG ranger module with display does not seem to be affected with this issue. It is perfectly fine to use these modules powered ONLY from the radio itself.
