testertest Posted July 21, 2023 Share Posted July 21, 2023 Hi all, I have an Armbian installed on Orange PI 4B. I am trying to connect a flight controller to Orange PI 4B by using UART port. This board has a 40 pin header. I went to armbian-config, and enabled the UART1 and UART 4 which are available from armbian-config. I plug the UART port (to Pin 8 and pin 10) on the 40 pin header. Is that port UART 4? I am not sure. It does not work. I tried the debug port, but the Orange PI does not start up if something is plugged in to the debug UART port. The PIN layout https://wiki.adopisoft.com/doku.php?id=4.0.0:gpio_numbering The layout of the board is similiar to Orange PI One. I know the 5 V location by using the case fan.

testertest Posted July 21, 2023 Author Share Posted July 21, 2023 I solved this issue. The manual from Orange PI does not come with clear GPIO pin definition. I should have used PIN #19 and Pin # 21, and the pin #1 is the top right pin. Thanks, 0 Quote Link to comment Share on other sites More sharing options...
