Overview
Blender macropad is an open-source printed circuit board by Wolf1no, from the Wolf1no/blender-macropad repository on GitHub. It is a 2-layer board of 98 × 99.2 mm with 33 parts on 34 nets, routed with 179 tracks and 1 via.
Its parts include 13 switches, 12 diodes, 2 resistors and 2 connectors. It belongs with the keyboards and input boards of this library.
README
README.mdBlender Macropad
Custom 12 key macropad with rotary encoder and OLED display, designed for better Blender workflow. Made for Half Life PCB project.
What is this
I am learning Blender and I have a TKL keyboard (no numpad), so viewport navigation is painful. This macropad gives me numpad keys (0-9, dot, enter) for viewport shortcuts, a rotary encoder for zooming/volume control and an OLED display for showing playing audio/telemetry
Hardware
- 12x Cherry MX compatible switches in 4x3 grid
- EC11 rotary encoder with push button
- 2.08" SH1122 OLED display (SPI)
- Pro Micro RP2040 (TENSTAR clone, mounted on back side, parts facing out)
- 3D printed case (designed separately)
How it works
Keys are wired in a 4x3 matrix with 1N4148 diodes which prevents ghosting (details in JOURNAL.md). The Pro Micro scans rows and columns to detect which key is pressed. Encoder uses two signal lines with 10k pullup resistors. OLED connects over SPI (5 pins).
Firmware runs KMK (keyboard focused layer). Bindings are fully customizable in code.py. OLED driver for SH1122 is not yet available in KMK, commented out in code for now.
Board
- Size: 98 x 99.2mm (2 layer, under JLCPCB 100x100 cheap limit)
- 4x M3 mounting holes
- Pro Micro USB-C aligns with top edge
- Diode direction: ROW2COL
Pin mapping
- Rows: GP2, GP3, GP4
- Columns: GP5, GP6, GP7, GP8
- Encoder: GP27 (A), GP28 (B), GP29 (click)
- OLED: GP22 (CLK), GP23 (MOSI), GP21 (CS), GP20 (DC), GP26 (RST)
- Power: 3V3 to VCC, all GND to GND
Build
- Order PCB from JLCPCB using gerber files in /gerbers
- Solder diodes, resistors, MX switches, encoder, pin headers
- Mount Pro Micro on back side (parts facing out, check TX0/RAW marking on silkscreen)
- Flash CircuitPython on Pro Micro RP2040
- Copy code.py and KMK library to the board
- Print case (STL in /case when available)

Questions
How big is the Blender macropad PCB?
It measures 98 × 99.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blender macropad use?
33 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Blender macropad KiCad files?
From the Wolf1no/blender-macropad repository on GitHub, at the commit this page was made from: the board is blender-macropad.kicad_pcb and its schematic blender-macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blender macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Wolf1no before reusing the design.
