The board was designed to be two Pi Zero sized boards or one over-sized board. In actuality, it is two prototyping boards that are connected together but easily broken apart. We acknowledge that the small Pi Zero footprint does not allow much room for additional circuitry. If you are okay with having an oversize board connected, leave the Schmartboard Pi Zero HAT as is for more working space…..or break them into two for double the fun. On one board we have standard 0.1” spacing with ground and 3 and 5 Volt rails. The second board has Schmartboard’s signature offset grid, a standard 0.1” spacing, offset by 0.05” with another standard row to give more flexibility
For your convenience, we have bundled it with a 2 x 20 male 0.1” spacing header and also a matching female 2 x 20 0.1” spacing header.
