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
4 VDD 3.0/5.0V Power supply
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.
SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus ).
8 RST   RESET (Low active)
