Board Layout

The EXT3 Touch board has three types of connection interfaces:

1. I2C header for directly controlling the Touch driver with your chosen EVK
2. ZIF headers for driving your chosen EPD with Touch capability. Each EPD+Touch attaches to two types of ZIF: 6-pin for driving the Touch IC and 24-pin for driving the EPD.
3. ZIF header for connecting the Touch board with the EXT3-1/EXT3 board. This comes supplied with an FPC.

An spare header space for 3.3 voltage output is also included.
