140-Piece U-Shape Breadboard Jumper Wire Kit for Arduino, Raspberry Pi & ESP32

U-shape breadboard jumper wires are pre-formed connection leads for making fast, tidy links on solderless breadboards, ideal for prototyping with Arduino, Raspberry Pi, and ESP32 projects. This 140-piece jumper wire kit helps you route power, ground, and signal lines between breadboard rows without cutting or stripping wire, making it useful for circuit testing, sensor hookups, logic experiments, and classroom electronics. The rigid U-style format keeps layouts organized and easy to trace, while the assorted lengths make it easier to bridge nearby or wider gaps for breadboard prototyping, module evaluation, and quick PCB design mockups.
