What is it?

Jumperless V5 lets you prototype like a nerdy wizard who can see electricity and conjure jumpers with a magic wand. It’s an Integrated Development Environment (IDE) for hardware, with an analog-by-nature RP2350B-based dev board, a drawer full of wires, and a workbench full of test equipment (including a power supply, a multimeter, an oscilloscope, a function generator, and a logic analyzer) all crammed inside a breadboard.

You can connect any point to any other using software-defined jumpers, so the four individually programmable ±8 V power supplies; ten GPIOs; and seven management channels for voltage, current, and resistance can all be connected anywhere on the breadboard or the Arduino Nano header. RGB LEDs under each hole turn the breadboard itself into a display that provides real-time information about whatever’s happening in your circuit.
