• PIC Output Expander

This Kit is designed to expand the number of outputs using serial data and clock from a micro-controller.   A single board has 4 x 74HC595 chips for 32 x low current logic outputs that can be used to control relay drivers and logic circuits, and further boards can be connected together to increase the number of outputs.  The outputs can be easily interfaced to transistors or MosFETs to switch relays etc. 

The Product image shows a fully constructed Kit product.  Please refer to the Options Tab for the descriptions of the various products available.
