Port Expander

Part of the pyControl behavioural experimental system

The port expander board expands a single behaviour port on the breakout board to 8 behaviour ports. It uses a serial to parallel IO expander (datasheet). It must be connected to a behaviour port with I2C (ports 3 and 4 on breakout 1.2).

 

!!! Electrical safety !!!

The port expander can draw power either from the the behaviour port or from a 12V power supply connected to the expander board using the 2.1mm barrel plug. See more
