Jacob just for info you can use a coin cell battery to determine whether your LED is common anode or cathode, centre positive or negative, simply slot it between the centre and an outer pin if it lights up with the + battery side touching the centre pin it’s common anode as required for GPCB circuits and visa versa with the minus side to centre pin making it common cathode
