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 Electronic Load PCB?
It measures 160 × 100 mm and has 4 copper layers, 1.56 mm thick.
What parts does the Electronic Load use?
114 parts, built around the SN65HVD232D, LM2904, LM358 and BSS138. 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 Electronic Load KiCad files?
From the Synthron/ModLab repository on GitHub, at the commit this page was made from: the board is Hardware/V3/Electronic_Load/Electronic_Load.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 Electronic Load design in my own project?
Its repository states no licence, so its author keeps all rights: ask Synthron before reusing the design.
