The Schmartboard Raspberry Pi Surface Mount Prototyping Board is the perfect way to add through hole components to a Raspberry Pi project. Schmartboard's signature offset through hole grid expands part placement options. An extra set of holes allows easy access to the GPIO header. Rows of power and ground traces make for easy, flexible power and circuit grounding. Pre-routed traces minimize the use of wire jumpers. Circuits for 4 level shifters allow additional devices regardless of signal values. Lastly, a marked area shows where the USB and Ethernet Connectors are located in order to avoid conflicts.
