Halpad

Halpad is a 9 key macropad with a knob and OLED designed around the idea of quickly selecting features.

Features:

• Simplistic case design
• 128x32 OLED Display
• EC11 Rotary encoder
• 9 Switches

CAD Model:

For the case, only M3x16mm and M3 heatset inserts are used for hardware, allowing for a simple BOM. It also only uses 3 3d printed parts for assembly, allowing for a quick and straightforward build.

Made in Fusion
