When working with prototypes, or wanting to add more than another Raspberry Pi add on can support, access to the GPIO pins are very limited.
So this handy board will split the current set of GPIO pins in to 2 headers, solderable by choice to add your favourite add on with an extra set of pins full labelled for adding extra LEDs, a second board or multimeter test probes - The possibilities are endless at how handy this can be.
1 PCB with full BCM and Board labelling - HAT sized to fit on any 40 way GPIO header
1 Female header for underneath to the Raspberry Pi
1 Male boxed header
1 Male 2 row pins
