Turn a tested breadboard circuit into a soldered Arduino-format prototype with this bare ProtoShield PCB. It is useful for robot interfaces that need to survive repeated handling better than loose jumper wires. In an education project, students can document the original circuit, transfer it carefully and compare the wiring against a schematic before power is applied. The product is a PCB for assembly, so component and header selection are part of the task.
Before you buy
