tooz 53 Posted June 21, 2023 hello @Alvin Kwek, there are 2 sets of uart on the 40pin header (uart0 & uart4), one is for console, and the other one will require pin soldering https://tinker-board.asus.com/images/doc/download/Tinker_Board_2_Schematics_20201214.pdf Share this post Link to post Share on other sites
