This repository contains the PSLab-Mini hardware design files. PSLab-Mini is a scaled-down version of the PSLab board, aiming to provide instruments for doing signal measurements. It consists of an Oscilloscope, a Logic analyzer, and a Multimeter.
It also integrates an ESP chip in conjunction with the main MCU(STM32), for enabling wireless connectivity via the board.

Questions
How big is the Pslab mini PCB?
It measures 85 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pslab mini use?
182 parts, built around the ESP32-C3, STM32H563RIT6, MT2496 and AMS1117-3.3. 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 Pslab mini KiCad files?
From the fossasia/pslab-mini-hardware repository on GitHub, at the commit this page was made from: the board is schematic/pslab-mini.kicad_pcb and its schematic schematic/pslab-mini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pslab mini design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
