From the project
PSLab Mini Hardware https://pslab.io
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.

Pslab mini hardware: common questions
What microcontroller does the Pslab mini hardware use?
The Pslab mini hardware is built around the ESP32-C3, from the ESP32 family.
How big is the Pslab mini hardware PCB?
The Pslab mini hardware measures 85 × 56 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Pslab mini hardware?
154 components, from 68 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Pslab mini hardware design files?
From the fossasia/pslab-mini-hardware repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Pslab mini hardware design in my own project?
Yes, under the terms of its Apache-2.0 license, which fossasia chose for the repository.
Can I test firmware for the Pslab mini hardware without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
