Cryptuino02: common questions

What microcontroller does the Cryptuino02 use?

The Cryptuino02 is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Cryptuino02 PCB?

The Cryptuino02 measures 43 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cryptuino02?

24 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Cryptuino02 design files?

From the hwreverse/PCBDesignLectures repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Cryptuino02 design in my own project?

Yes, under the terms of its BSD-3-Clause license, which hwreverse chose for the repository.

Can I test firmware for the Cryptuino02 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.
