Pins to use for connecting serial device to Bela Mini?

m3rten

Dear forum,
I have a Serial device that I want to connect to my Bela Mini (using an RS232 to TTL converter). As far as I can see there are 3 sets of RX/TX pins for UART (UART0, UART2 and UART4). Which ones should I use? And how do I specify the pins in my Render file? I tried to look at the Serial library, but couldn't make it out.
Thanks a lot!

UART4 is the best one because all its pins are available. In your render file you only select the peripheral (/dev/ttyS4 for UART4). The pins (P2.05 and P2.07) are already set to those signals so you should be fine.
