The IO Zero 32 is supplied with the 40 pin GPIO connector unsoldered. Before using the IO Zero 32 you will need to solder the connector onto the PCB. The power link and I2C address selection are configured using solder jumpers. For your convenience we supply the IO Zero 32 with the power link jumper and one address selection jumper pre-soldered.
The digital input pads are spaced 2.54mm apart. You can solder wires directly to the board or use 2.54mm pitch headers. The IO Zero 32 is compatible with 40 pin IDC vertical and right angle headers allowing you to use ribbon cables to connect your external devices to the board.
Note: When stacking the IO Zero 32 with other boards a right angle header is recommended for the I/O pins.
To install the IO Zero 32 simply press the 40 pin connector down onto the Raspberry Pi GPIO pins with the board sat over the top of the Raspberry Pi.
If you are installing more than one IO Zero 32 on a single Raspberry Pi board then you will need to configure the address select jumpers for each IO Zero 32.
Remove the isolation jumper when connecting an external power supply to the V+ and GND pins.
