Differences Between Jumper T20 V1 and V2

We have had a few questions from our customers asking about the differences between the V1 and V2 of the T20 ELRS radio from Jumper.

There are two main changes

  • move the ELRS module link to an UART with DMA so that faster link speed can be achieved (1.87 mbps up from 921k)
  • support for ELRS passthrough programing

Hope that helps!
