2 layers57.3 × 61.8 mm SabhyaPad, the printed circuit board in 3D

SabhyaPad

This is my own MacroPad, called SabhyaPad! It has 6 buttons that can easily be customized using QMK. Using it is really simple: just plug a USB-C cable into your computer, allow it to connect, and then start using it.

I made this so that my life is easier. Currently, it is configured to do this...

Here is a video of it on YouTube!!! I accidentally put the wrong link in the demo section actually...

Assembly

For assembly:

3D Print the case cut file.
Take your soldered PCB and push it into the top part. It will click and then it will be attached.
Take the bottom part and put it at the bottom.
Use M3x16mm screws and the M3 nuts to enclose it.

Firmware

The SabhyaPad firmware is based on QMK Firmware and is located in:

text

FIRMWARE/sabhyapad

Requirements

Install QMK MSYS from:

https://qmk.fm

After installation, open QMK MSYS and verify it is installed correctly:

bash

qmk --version

Setting Up QMK

Clone and set up QMK Firmware:

bash

qmk setup

Installing SabhyaPad

Navigate to the keyboards directory:

bash

cd qmk_firmware/keyboards

Clone this repository:

bash

git clone https://github.com/SabhyaAggarwal/SabhyaPad.git

Building the Firmware

Return to the QMK root directory:

bash

cd ../..

Compile the firmware:

bash

qmk compile -kb sabhyapad -km default

Or:

bash

make sabhyapad:default

Firmware Output

A successful build will generate:

text

sabhyapad_default.uf2

Since SabhyaPad uses an RP2040 microcontroller, the firmware is generated in UF2 format.

Flashing the Firmware

Hold the BOOTSEL button while plugging the keyboard into your computer.
A drive named RPI-RP2 will appear.
Drag and drop:

text

sabhyapad_default.uf2

onto the drive.

The keyboard will automatically reboot and start running the new firmware.

Updating

Pull the latest changes:

bash

cd qmk_firmware/keyboards/SabhyaPad
git pull

Rebuild:

bash

cd ../..
qmk compile -kb sabhyapad -km default

Troubleshooting

Check your QMK installation:

bash

qmk doctor

Clean and rebuild:

bash

qmk clean
qmk compile -kb sabhyapad -km default

List available keymaps:

bash

qmk list-keymaps -kb sabhyapad

Quick Start

bash

qmk setup

cd qmk_firmware/keyboards
git clone https://github.com/SabhyaAggarwal/SabhyaPad.git

cd ../..

qmk compile -kb sabhyapad -km default

Questions

How big is the SabhyaPad PCB?

It measures 57.3 × 61.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SabhyaPad use?

8 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 SabhyaPad KiCad files?

From the SabhyaAggarwal/SabhyaPad repository on GitHub, at the commit this page was made from: the board is PCB/SabhyaPad.kicad_pcb and its schematic PCB/SabhyaPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SabhyaPad design in my own project?

Its repository states no licence, so its author keeps all rights: ask SabhyaAggarwal before reusing the design.
