RN4871 bluetooth module
I had already made the ESP8266 module. It is a wifi module and I had success connecting to Blynk.app using it. But Blynk is expensive and I’ve decided that using a different module is probably better. I’m creating a RN4871 board to have a bluetooth module instead of wifi. I found the board on the Fab Academy website and modified so I had more pins available if needed later in the process.
