A modular station for your electronic workbench
The ModLab is designed to be housed in a 19" Rack with 3U.
It is the improved version of the (failed) Arduino Workstation I built a long time ago.
But now It will be bigger, better and way too complicated.

Questions
How big is the ModLab PCB?
It measures 160 × 100 mm and has 4 copper layers, 2.61 mm thick.
What parts does the ModLab use?
211 parts, built around the ESP32-WROOM-32, MAX485ED, SN65HVD232D and LM2904. 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 ModLab KiCad files?
From the Synthron/ModLab repository on GitHub, at the commit this page was made from: the board is Hardware/V3/Mainboard/V2/Mainboard.kicad_pcb and its schematic Hardware/V3/Bustermination/Bustermination.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ModLab design in my own project?
Its repository states no licence, so its author keeps all rights: ask Synthron before reusing the design.
