Slick Keyboard Constructed With PCB Magic


Typically an opportunity dialog leads you to find one thing cool you’ve not seen earlier than, and earlier than you already know it, you’re ordering components for one more {hardware} construct. That’s what occurred to this scribe the opposite day when chatting on some random discord, to QMK maintainer [Nick Brassel aka tzarc] about Djinn, a stunning 64-key cut up mechanical keyboard testbed. It’s a testbed as a result of it makes use of the most recent STM32G4x microcontroller household, and QMK at the moment doesn’t have help for this within the mainline launch. In the intervening time, [Nick] maintains a customized launch, till it will get merged.

{Hardware}-wise, the design is fabulous, with quite a lot of consideration to element. We have now particular person per-key RGB LEDs, RGB underglow, a rotary encoder, a five-way tactile thumb swap, and a 240×320 LCD per half. The keyboard is predicated on a 3 PCB stack, two of that are there purely for construction. This slick design has sufficient options to maintain a good few of us completely satisfied.

Curiously, once you take a look at the design recordsdata (KiCAD, naturally) [Nick] has chosen to take a mirrored strategy to the PCB. Meaning the left and proper sides are literally the identical PCB format. The elements are populated on totally different sides of the PCB relying on which half you’re ! By mirroring footprints on each PCB sides, and hooking every thing up in parallel, it’s doable to do all of it with a single grasp format.

It is a easy however genius concept that this scribe hadn’t come throughout earlier than (the disgrace!) Secondarily it retains prices down, as your typical Chinese language prototyping home won’t deal in PCB portions under 5, so you can also make two full keyboards on one order, slightly than needing two orders to make 5. (Sure, there are literally three distinctive PCBs, however we’re simplifying the state of affairs, okay?)

Now, if solely this pesky electronics scarcity may abate a bit, and we may get the components to construct this magnificence!

Clearly, we’ve coated many, many keyboards through the years. Right here’s our personal [Kristina’s] column all concerning the issues. Should you want a little bit assist together with your typing abilities, this surprising instance stands out as the one for you. In case your style is correct old-school clackers, there’s one thing for everybody.
