README

syvrcpad

I made this because I wanted to try something new and to feel useful to myself 💀 and ofcourse to make something which I would use in my daily life to probably save some extra clicks and miliseconds.

syvrcpad is a 4x3 (4 by 3) macropad with a rotary encoder E11 and has 0.91 OLED Display. The macropad uses XIAO RP2040 as its micro controller.

build

well um yeah 💀, this is not soldered btw, i jus added switches and the xiao to it cuz it looks cool sybau and ooh also i made use of an old charger cable of my phone

i originally did not have a soldering iron/kit but then i did #solder and got one, turns out the whole soldering iron of the kit is messed up which took me 5 diodes, 3 pcbs and the whole solder wire of the kit to figure out. and i crashed out bad, anw now idts i will be able to make ts so now im working on a keeb called syvrcboard v0 with an integrated macropad boii

Schematic

PCB

PCB Front	PCB Back

I had the most fun making schematic and PCB, tho I had to do both of these quite a lot of time 💀 I have routed the PCB like minimum 8 times if not more. Being a complete beginner and having no clue what you are doing is really fun, I am pretty sure I annoyed hell lotta people in the #highway and #hackpad channel lmao and special thanks to @Ayo, @Domain and @Cyao (on slack) and many other people who helped me through this journey and making this project possible.

Layers

My initial plan was to make Top, Middle and Bottom layers but I just ended up with Top and Bottom layers because it was taking way too much time than expected and planned. Im pretty happy and proud of what I have made btw 🗣

Thickness of Plate: 1.5mm
Thickness of Bottom: 10mm

Render of the PCB with all the components

Side View

Made the USB C port more accessible and ofcoure more visually appealing

Closing and Thank You!

Being able to do something like this was REALLY fun, loved and enjoyed every second of it
Learned some basics of Kicad
Learned Shaper3d (moderately)
Learned what a Keyboard matrix is and how it works
Learned few keyboard mounting methods
Maybe it was the friends we made throgh the journey
