All the electrical designs for MECSEM.

KiCad sources for all the PCBs in the microscope.

This repository contains only the electrical design: schematics, PCB layouts, and KiCad symbol/footprint library.

A Linux Mint host PC inside the chassis (powered by the in-chassis PicoPSU) commands two central RP2350 controllers over USB:

HV Controller: the master optics-column controller. Drives source bias, lenses, deflectors, the scintillator detector, raster scan, and the PMT readout. Bridges the floating cathode side onto USB. LV Controller: the vacuum subsystem state machine: roughing pump, turbopump VFD (RS-485), isolation valve…
