Jumperless is a breadboard that makes real hardware connections between any points on the board, or the Arduino Nano header at the top via software command, instead of needing to use jumper wires.
It can be used to probe the pins on an unknown IC, or for some automated fuzzing, or to read/write EEPROM chips, or to help guide you through converting a schematic to a real circuit, or do whatever the hell you want with it.
Jumperless also has a ton of voltage/current sensing so the RGB LEDs underneath each row can show a ton of information about what's going on with your circuit. 2 buffered high-current DACs (one 0-5V and one ±8V), 4 buffered and level-shifted 12-bit ADCs (3 are 0-5V and 1 for ±8V), 2 INA219 current and voltage measurement ICs, and 5 GPIO to simulate digital signals that can be routed to anywhere on the breadboard or the Arduino Nano header (also broken out to the top left corner for doing other things.)
The connections are real and fully analog (-8V to +8V, up to around 1 MHz before signal quality starts to degrade) instead of cheating with some measure-then-simulate setup, although you can do that too if you want to simulate a memristor or to send jumpers over the internet.
