I recently bought several Lafvin Nanos for a STEM camp I'm doing in which we are building some robots. The prototype I built uses a different brand Nano that I had on hand. When I plug it in and choose the port only one shows up (dev/cu.usbserial-A9473TXD). All my sketches load just fine.
However, when I use the Lavfin board, two ports show up (dev/cu.usbserial-1420 and dev/cu.wchusbserial1420). It doesn't matter which port I use, the sketch always fails to upload.
Can someone point me in the right direction? Thanks!
