BPI P2 ZERO UART Communication

Hello, I installed armbian on BPI P2 Zero (EMMC), and I was trying to communicate by UART with a speed radar. I went to armbian-config to enable UART 3, and also I Added overlays= uart3.

The radar is connected to pin 8, 10 and GND, but it doesn’t work.

Anyone knows what I am doing wrong?

Regards.

Try armbian forum perhaps?

Hello Igor,
