Ryde GPIO breakout

To help constructors connect easily to the Ryde RPIO, BATC has produced a small daughter board - PCBs will be available in the BATC shop.

Construction notes

• Note the GPIO board requires 5v NOT 12v!

• The GPIO header is placed on the opposite side of the PCB to the rest of the components.

• Pay attention to the orientation of the resistor arrays - they are not the same.

• Build the top side first, start with the resistors, then the resistor arrays, then the 16 way, then the headers, finally fit the 40 way on the other side of the PCB.

• The fuse is a standard automotive mini-blade, 3A. Take care inserting it as it requires considerable force. You may need to open up the socket a little.
