[newbie] What is that plug on the TTGO?
Posted: Tue Jan 18, 2022 10:00 pm
Hello,
I don't know much about embedded, and this is the first time I'll be using an ESP-based micro-controller (to build a DIY CO2 box).
I just bought this TTGO and intend to connect it to a Senseair CO2 sensor.
What is this plug for?
(I guess RST stands for Reset, ie. reboot the controller; In addition, there are two programmable buttons named GPIO 0 and 35.)
Thank you.
