About the Numpad PCB

Numpad is an open source PCB design by mouse625, published on GitHub under the MIT license. It is a 2-layer board measuring 67.1 × 85.7 mm, with 21 components from 3 distinct parts.

Other key parts include the MOUDLE-SEEEDUINO-XIAO. By type, the board carries 10 switches, 10 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

A custom macropad (which functions as guess what, a numpad) created for Hackpad (a mission for Stardance, an event run by Hack Club).

Numpad is a Macropad, a custom sort of mini-keyboard usually designed for faster inputting of hardcoded shortcuts/strings or specific functions. However, this macropad is made as a Numpad accessory for inputting an assortment of Unicode characters.

This project is made possible by Hackpad, a YSWS (you ship we ship) event on making a custom Macropad run by Hack Club.
