Configuration
To resolve library dependencies in KiCad, you must configure the OXEBOTS_SSL_LIB_DIR path variable:
- Open KiCad.
- Go to Preferences > Configure Paths...
- Add a new entry (+ symbol):
- Name:
OXEBOTS_SSL_LIB_DIR - Path: Path to the
Librariesfolder in your local machine.
- Name:
This ensures all schematic symbols, footprints, and 3D models are correctly linked.

Questions
How big is the Kicker LT3751 OxeBots PCB?
It measures 114 × 135.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kicker LT3751 OxeBots use?
126 parts, built around the TLV9002ID, LM358, AQV454HAX and HCNR201. 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 Kicker LT3751 OxeBots KiCad files?
From the OxeBots/ssl_electronics repository on GitHub, at the commit this page was made from: the board is pcbs/kicker/Kicker_LT3751_OxeBots.kicad_pcb and its schematic pcbs/kicker/Kicker_LT3751_OxeBots.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kicker LT3751 OxeBots 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).
