Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| GND | Ground | GND | |
| VCC | Power | 3V3 | |
| SCK | SPI clock | D18 | |
| CS | SPI chip select | D5 | |
| SO | SPI MISO | D19 | Data out of the module (SPI MISO) |
| TC+ | Not wired to the ESP32 | — | Thermocouple + (screw terminal) |
| TC- | Not wired to the ESP32 | — | Thermocouple - (screw terminal) |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
