SPECIFICATIONS
Interface Pin Function
| No. | Symbol | Function |
|---|---|---|
| 1 | VCC | Power supply input: 2.9 – 5.2V |
| 2 | GND | Ground |
| 3 | SCL | When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance. |
