Github repository dedicated to the mooltipass project

Mooltipass Project Repository ============================= This is the GitHub repository dedicated to the Mooltipass device family. It contains all the resources that were used and made for this community driven product line since the project was first started back in December 2013. The Mooltipass Mini device is available for purchase on our Tindie store.

What is the Mooltipass Project? ------------------------------- With time, logins and passwords have become critical elements we need to remember to access the different websites and services we use daily. If we want to achieve good…

Mooltipass mini: common questions

What microcontroller does the Mooltipass mini use?

The Mooltipass mini is built around the ATMEGA32U4_QFN, from the AVR/Arduino family.

How big is the Mooltipass mini PCB?

The Mooltipass mini measures 74.9 × 32.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mooltipass mini?

65 components, from 29 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 Mooltipass mini design files?

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

Can I use the Mooltipass mini design in my own project?

The repository has no license, so all rights stay with limpkin. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mooltipass mini 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.
