Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| E | Input (the ESP32 drives it) | D25 | Segment: LOW = on. Each segment through a 220 Ω resistor |
| D | Input (the ESP32 drives it) | D26 | |
| COM | Power | 3V3 | Common anode: to 3V3 |
| C | Input (the ESP32 drives it) | D27 | |
| DP | Input (the ESP32 drives it) | D32 | Decimal point |
| B | Input (the ESP32 drives it) | D33 | |
| A | Input (the ESP32 drives it) | D23 | |
| COM2 | Power | 3V3 | Second common pin, same as COM |
| F | Input (the ESP32 drives it) | D19 | |
| G | Input (the ESP32 drives it) | D18 |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
