AtreuSLB50+ rev1

AtreuSLB50Plus / AtreuSLB50+ rev1

Finally I had the time to wrap up my little side project started about three months ago, and I thought to share it here. Although inspired by the Atreus, I couldn't quite find the right compromise among the non-split ergo keyboards, so I decided to make my own.

Features:

• 1x RP2040 (KMK on Raspberry Pi Pico), USB-C port
• 50x switches
• 1x SSD1306 128x64px 0.96in IIC OLED display
• 2x EC11 rotary encoders
• 1x EVQWGD001 rotary encoder
• 1x Pimoroni IIC trackball breakout
• 1x Active buzzer
• 2x micro switches (bootsel, reset)
• 3D printed case (5-10° tilt), plate, pcb

Name is lame, might change it later. That's all for now.

Post-Printing

M3 hex bolts and inserts are needed to put the case together.

I also melted the two bottom halves together with a soldering iron.

How I Designed This

The design started from a semi-automated customised process by forking an OpenSCAD hotswap pcb generator repository, subsequently heavily worked on Blender. I had also added cutouts for per-key rgb, but in the end I gave up the idea of hand wiring the LEDs. At least in this version which, for me, has been an insightful experience.
