Mathpad
Summa Cogni's Mathpad is a dedicated device that makes it easy to type equations.
Published June 4, 2025
The tiny Mathpad, released by Summa Cogni's Magne Lauritzen, is a macropad intended for engineers, scientists, students, and professionals in STEM fields who regularly need to write equations or who use mathematical symbols in their day-to-day work. It uses the power of Unicode to output potentially every symbol in existence.
With the Mathpad you can type 112 symbols from algebra, calculus, set theory, and logic, and the full greek alphabet – Summa Cogni.
If you know the project by a different name (e.g. Mathboard), Mathpad had to be renamed right after ordering prototypes. Yikes!

- 16 keys
- low-pro Gateron K-33 switches, hotswap
