Scrabblepad: common questions
What microcontroller does the Scrabblepad use?
The Scrabblepad is built around the Teensy++2.0, from the NXP family.
How big is the Scrabblepad PCB?
The Scrabblepad measures 285.8 × 285.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Scrabblepad?
475 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Scrabblepad design files?
From the DonutCatDev/ScrabblePad-Kicad-Files repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Scrabblepad design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Scrabblepad without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
