TutelPad: common questions

What microcontroller does the TutelPad use?

The TutelPad is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the TutelPad PCB?

The TutelPad measures 61.9 × 65.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TutelPad?

38 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the TutelPad design files?

From the 0xCB-dev/0xCB-TutelPad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TutelPad design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the TutelPad without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
