It is built around the LNK3206D-TL, 1N5231B and SA5.0A-TP. Its parts include 16 capacitors, 15 diodes, 14 resistors, 3 connectors and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Welcome to the Motorized Bike Ignition Systems (MBI) repository! This open-source project aims to provide a comprehensive solution for motorized bike enthusiasts, offering a reliable and customizable ignition system.
Motorized Bike Ignition Systems (MBI) is an open-source project focused on developing high-quality ignition systems for motorized bikes. Our goal is the development of new CDI technology, tools for evaulating them, and providing open and closed source CDIs for motorized bike engines.
There are a few ways you can go about acquiring a CDI. You can:
Since this is an open-source passion project, we are adding information when we find time to. The wiki will start to get more and more information as we build more testing equipment and gather more knowledge from the community. If you think that there's more to add then consider becoming a contributor or donating to the project!
This project is licensed under the GPLv3 License. Feel free to use, modify, and distribute the designs in accordance with the terms outlined in the license.
If you find this information helpful then consider contributing to the project! All donations go towards contributing to this repo and developing open source devices to add.

It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
56 parts, built around the LNK3206D-TL, 1N5231B and SA5.0A-TP. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the MBI-Ignitions/MBI_Ignition_Systems repository on GitHub, at the commit this page was made from: the board is Open Source CDIs/UnoShield/unoShield.kicad_pcb and its schematic Archive/Mk1/Mk1 SMD/Mk1CDIs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
