The Braun is a simple, straightforward 4-channel oscilloscope, meant to fill the gap between low-cost 1-channel scopes (such as the Hagiwo) and expensive scopes like the Mordax Data. The analog front-end is a simple scale and offset with fixed attenuation (It can be changed in hardware though) and no hardware triggering. It features a RP2040 processor (meaning some mathematical operations like FFT are possible but also visualizers), a 320x240p IPS display and USB-C. The Reset and Boot button are also mounted to front, meaning you never have to remove the module from your rack when writing firmware :) The frontjacks are connected directly to each other (without buffering) so it doesn't really matter which one you use as input. It is compatible with both Arduino and CircuitPython, offering a friendly programming environment. The flash size is 128Mbit, meaning there is ample space for storing data.

These are the through-hole parts that you need to add to finish the build. See Github for additional details.
