Pinout
12| Pin | Name | Functions | Notes |
|---|---|---|---|
| VIN | power | POWER | The power pin. To power the board, give it the same power as the logic level of your microcontroller - e.g., for a 5V microcontroller like Arduino, use 5V. |
| VIO | digital_power_supply | GND | Output from the on-chip power supply regulator for the digital power supply. |
| GND | ground | GND | Common ground for power and logic. |
| A+ | hx711_channel_a_positive_input | GPIO | Channel A positive input. You'll connect the green wire on your strain gauge to this block. |
| A- | hx711_channel_a_negative_input | GPIO | Channel A negative input. You'll connect the white wire on your strain gauge to this block. |
| B+ | hx711_channel_b_positive_input | GPIO | Channel B positive input. This is a secondary input for the HX711. |
| B- | hx711_channel_b_negative_input | GPIO | Channel B negative input. This is a secondary input for the HX711. |
| E+ | hx711_analog_power_output | GND | Connected to the analog power output. You'll connect the red wire on your strain gauge to this block. |
| E- | hx711_common_ground | GND | Connected to common ground. You'll connect the black wire on your strain gauge to this block. |
| SCK | serial_clock_input | SPI | Serial clock input. |
| DATA | serial_data_output | SPI | Serial data output. |
| RATE | rate_selection_switch | GPIO | Output data rate control. If this pin is low, the data rate is 10 SPS and if the pin is high, the data rate is 80 SPS. |
