what is the difference between the v1 and v2 TBS CROSSFIRE MICRO Receivers?

TBS CROSSFIRE MICRO RECEIVER V1:
- 1 output channel
- Output mapping options: PPM, SBUS and CRSF (RC only, no telemetry)
- BST telemetry support (TBS GPS, TBS CORE PRO, TBS FPVision layer, TBS POWER CUBE )

TBS CROSSFIRE MICRO RECEIVER V2:
- 4 output channels
- Output mapping options: PWM, PPM, SBUS, MAVLink and CRSF (see output mapping options of output 1 or 4 )
- Full MAVLink support using output 3 and 4
- Full CRSF support (RC and telemetry) using output 1 and 2
- BST telemetry support (TBS GPS, TBS CORE PRO, TBS FPVision layer, TBS POWER CUBE )
- Comes with 4 channel servo adapter


The main difference is the v2 has a 4 channel pwm output.
Both have a BST telemetry connection but it won't work with Betaflight (yet).
