Recently flying my nano quad, felt a bit scary without a second receiver on the goggle. I had to keep moving my head to get the best reception for the video feed. Finally, I learned about the little display thing on every one’s FPV goggle is actually dual RX5808 receiver with some firmware that keep switching to the best video feed signal. My Eachine EV-100 having dual antenna but is not a very good in handling diversity. I found a few good opensource projects and saw their designs very good but I need audio output as well for the receiver so decided to make my own version. The board already sent for fabrication and now left the firmware to be developed and make it working. I had already tested the tv composite output is working and is very fun to built this diversity vtx receiver. Wish me luck!
