I had a busy week this last week. I was finally able to get some of my latest board designs posted for sale in my online stores.
Below are pictures of the four boards I added. The first picture shows them all stacked on top of the Raspberry Pi. The red and black wires supply 12 volt DC to run relays and motors. The second photo shows the individual boards. These boards are, starting clockwise at the top left corner: 8 digital inputs and 8 outputs, 8 channel stall motor controller to control model railroad switch machines, 16 digital outputs, and 16 digital inputs.
So you can mix and match these boards depending on your controller needs.
