Document wiring diagram #2

Open goatchurchprime opened 5 years ago

goatchurchprime commented 5 years ago

On TTGO no oled board, with Lora aerial:

Power from cell to JST connector Switch: G and 3V and middle pin to pin13 GPIO_NUM_13

Solder points directly to short wires. No pullup/down resistors, as the switch jumps directly between G and power. Therefore no power leakage.

Might be worth us verifying there is no potential for leakage on the pin due to the pin configuration
