Is the Jumper T20 gemini supported?

You can flash it with the generic and then ESP32 based.

As far as i know it uses additional ESP8285 for espnow, right?

[pkendall64]

Yes, the code runs on the ESP8285 (backpack) but talks to the ESP32 (main ELRS MCU).
Select the following options in the backpack firmware upload section of configurator.

Ok. If I understand correctly, it should look like this: [Jumper T20] <-CSRF-> [Internal ESP32 RX] <-UART-> [?additional ESP8285 device?] <- ESP Now-> [Steadyview ELRS VRX].
