# Jumperless
https://user-images.githubusercontent.com/20519442/227739104-85ad8e68-dfe9-4510-ad2b-4cc7110a7baf.mov
This is a new revision of [breadWare](https://github.com/Architeuthis-Flux/breadWare) with a new name.
That repo has a lot more info that generally applies to this one too, so go read that if you'd like to know more about this thing.
I'm basically rewriting that whole codebase from scratch because it's kind of a mess. So the new stuff will go here.
## Here's the general vague roadmap (for anyone who wants to contribute):
An Arduino library for commanding the RP2040
A circuitPython library to do connection stuff.
(optional) a custom GUI for making connections
(optional) Component placement sensing or just a simple way to define part locations
### a jumperless breadboard

Using a bunch of analog crosspoint switches wired together into one bigger switch, this breadboard 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.

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 4 GPIO to simulate digital or analog signals that can be routed to anywhere on the breadboard or the Arduino Nano header.

Use it to probe the pins on an unknown IC, or for some automated fuzzing, or to help guide you through converting a schematic to a real circuit, or do whatever the hell you want with it.

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](https://en.wikipedia.org/wiki/Memristor) or to send jumpers over the internet.

And no, it's not an FPGA.
