BoardPilotTM1637 6-digit 7-segment display with ESP32
Supply 3.3-5 V
Bus GPIO
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| CLK | Input (the ESP32 drives it) | D25 | Pin order varies between boards: match by the printed label. Clock (not I2C, not SPI) |
| DIO | Input (the ESP32 drives it) | D26 | Data (not I2C). Digits may be wired out of order: libraries have a setting for it |
| GND | Ground | GND | |
| VCC | Power | 3V3 | Works at 3.3 V or 5 V |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
