- Sun Dec 11, 2016 5:53 pm #59371 I'm working with this ESP-01 module, using the arduino IDE, and I've come across an odd issue. If LED_BUILTIN is set to an output, the serial console doesn't work. Is this a known issue, or something odd about this board? It's ended up costing me way too many hours figuring out.

EDIT: Never mind, I found this documented elsewhere.
