A4 P24
A5 P25
b﴿ When the pins A0‐A5 are connected to 3, they will sever as ADC pins.
You can also connect the pin A4 to P_SCL, and the pin A5 to P_SDA ﴾as the figure shows﴿, to
making them sever as I2C control pins of Raspberry Pi board. However, in default settings, the pins
A4 and P_SCL are disconnected, and so do the pins A5 and P_SDA.
Notices: Users can modify the settings of these jumpers as required. In this operation,
welding is required. Any changes under no guidance from Waveshare will be considered as
a waiver of warranty.
Setting the pins A4 and A5 as I2C control pins
ARPI600 provides sensor interfaces 4P. The figure shows the jumper settings for sensor interface
4P.
Sensor interface 4P
In which:
The pins on A are connected to the ADC pins A6‐A10 of TLC1543;
The pins on D are connected to the IO control pins P0‐P4 of Raspberry Pi board.
Users can apply different sensors via the sensor interface.
