Esp32_pins - lefty01/ESP32_TTGO_FTMS GitHub Wiki
Table over GPIO pins on different boards used in the project, Note: some pins are both routed out and used on the boards.
| Symbol | Explanation |
|---|---|
| * | Main (bottom) connector of board |
| ** | Secondary connector, like the I2C on T4 |
| (TEXT) | TEXT is on the dev board itself, like screen, some buttons, touch |
| TEXT | TEXT is something we connected in the project |
