Pinout for A02 VTX
Noticed: When you solder the VTX, pls follow the diagram for A02 VTX, in which the second port under ANT(MMCX) is GND, and it corresponds to the black wire of the 6-Pin FC Cable. If you have received the VTX with a diagram of "SW" or just black in the GND place, Please don't worry, it's just the typographical error, we have corrected it in the next batch.
How to Connect with FC
Here is an example of how to connect the A02 to a flight controller.
How to Use the Pit Mode & Change the Frequency and Power
PitMode allows racers to power up their video transmitters during race events without interfering with other racers, and it still has the ability to change VTX settings or do some testing. The range is limited to 2-3m and transmission happens on the selected frequency.
The PitMode is active when theRed/Green/Blue Power LED flash.
How to active and exit the PitMode
Press the Button on the VTX twice to active Pitmode, double-press again to return to the previous power state.
How to Change Frequency & Channel & Power
Enter the OSD menu by radio transmitter sticks ( Pitch Stick UP and Yaw Stick Left). Then FEATURES -> VTX SA to change the frequency and power.
Switchable power includes 25mW, 200mW, 500mW and 800mW, and the PitMode is supported on this VTX.

Handy as a second transmitter for travel, tiny whoops, etc
Surprisingly good for the price especially with ELRS. It has just enough switches that I can do most of what I can with the TX16S, and it's so much easier to throw in a bag and go. My only wish is that I could put the thumb-grippies style of stick ends on it easily (and still remove them for storage), but maybe someone will come up with an adapter or similar. Next step is to try a Gemini ELRS nano module and see what kind of range is possible on that.
