Hi !
I bought this kit and tried the demo setup, with 4 buttons on the Tx, and 5 LEDs on the Rx.
As shown on photos, I used 9V batteries. And nothing works…
Here I see that 9V is too much for the Rx ? So did I kill mine ?
What are the real power requirements for both Rx and Tx please ?
Thanks and sorry if my english is bad, I’m french…
