  • I am trying to establish uart between arduino mega and gsx breakout board. I have simple voltage divider for tx/rx and is using Serial3 at 9600. It doesn’t seem to be working and I am wondering if I have mistakenly burnt the board by applying 5V DC to either tx/rx. Is there a way to test this? In this case, UART wouldn’t simply work?

No public wish lists :(
