This repository contains the source files for the CanLite, an ESP32 based CAN development/hacking board which features a built-in automotive grade dc-dc converter as well as an optional two channel high-side automotive grade switch capable of switching up to 1.8A per channel with plenty of protection features.
More info about this project in Voltlog #370 & Voltlog #390. If you would like to order one of these boards ready assembled, check out my Tindie store.
Changelog
- revD: Switched to a different inductor, different high-side switch, optimised layout.
- revC: Switched to a different inductor pn, added some IO access via test points.
- revB: Fixed some bugs from revA.
- revA: Initial release.

Questions
How big is the CanLite PCB?
It measures 40 × 53.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CanLite use?
42 parts, built around the ESP32-WROOM-32D, SN65HVD231D, SS14 and BAS40-04. 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.
Where can I download the CanLite KiCad files?
From the voltlog/CanLite repository on GitHub, at the commit this page was made from: the board is CanLite.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CanLite design in my own project?
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).
