Supply 3.3-5 V
Bus GPIO
Measures pressure
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| VCC | Power | 3V3 | Pin order differs between sellers: check the silkscreen |
| OUT | Output (the part drives it) | D25 | Data out of the HX710B |
| SCK | Input (the ESP32 drives it) | D26 | Clock driven by the ESP32 (not SPI) |
| GND | Ground | GND |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
