Interface Pin Function
Pin No. | Symbol | Level | Description |
---|---|---|---|
1 | VOUT | DC/DC voltage converter. Connect a capacitor between this terminal and VIN when the built-in booster is used. |
|
2 | CAP1N | For voltage booster circuit(VDD-VSS) External capacitor about 0.1u~4.7uf |
|
3 | CAP1P | ||
4 | VDD | 3.0/5.0V | Power supply |
5 | VSS | GND | |
6 | SDA | (In I2C interface DB7 (SDA) is input data. SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus ). |
|
7 | SCL |
(In I2C interface DB6 (SCL) is clock input. |
|
8 | RST | RESET |
