Communication Header Pinout
The 20 pin FFC header on the EVE2 TFT Module is used to interface with an SPI controller, and is compatible with a
number of 20 pin ribbon cables. Any 20 pin FFC cable with a 0.5mm pitch and bottom contacts, such as the Wurth
Electronics INC 687620050002 series ribbon cable will be compatible with the EVE2 module.

*Note:
The CS pin signifies when a SPI transaction occurs by going active low. When the pin goes inactive high, the write
operation is considered complete.
**Note:
Open drain output (default) or push-pull output, active low
