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.\u003c\/p\u003e\n\u003cp\u003eYou 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.

The firmware has a persistent flag so it knows this and routes accordingly.
