Ingenuity-Pad

Ingenuity is a 8 key macropad with a rotary encoder and per key customizable lighting. It uses QMK firmware and it via compatible. It is heavily inspired off the Treasure Type 9 series.

Features

• EC11 Rotary Encoder (For Volume Control)
• 8 Keys
• A beutifull case
• Via support
• Per key customizable RGB lighting through VIA

CAD Model

Everything comes together using 4 M2x8 screws. They are screwed in from the plate into the main case. It has 2 peices the plate (for holding switches) and the main case (for everything else) <image src=/assets/cad.png/> Made in onshape, left fusion because it kept on crashing on my mac.

PCB and SCH

This is my PCB and SCH. It was made in KiCad and the silkscreen was made in figma. PCB <img src=/assets/pcb.png/> SCH <img src=/assets/schematic.png/> The routing was really hard to get used to, but in the end (after like 100 redos), I made it.

Firmware

It uses QMK with via for everything

• the rotary encoder is used for RGB hue
• and the other keys are routed to similar rgb controls
• there are 2 layers one of which is the rgb control and the other is function keys (i plan to add more later on)

BOM

• 8x Cherry MX Switches
• 8x DSA Keycaps
• 4x M2x8 screws (i'll get them from home depot)
• 9x Diodes
• 1x EC11 Rotary Encoder
• 9x LEDs
• 1x XIAO RP2040
• 1x Rotary Encoder Keycap cover

other stuff

btw this took me like months (from v1 to v3), i went through like 17 iterations before this, thx hc!!
