PSLab Electronics Lab Board is Now Available for $65

Pocket Science Lab (PSLab) is an open source hardware USB board that aims to bring electronics labs to the masses, as it can act as an oscilloscope, voltmeter, programmable voltage and current source, logic analyzer, or signal generator when connected to a PC or mobile phone.

This is not professional equipment, and instead designed for STEM education. When we first covered the board in August, it was still in development, but I’ve just found it is now listed and in stock on Seeed Studio for $64.90.

PSLab Android App

The board can be used through a computer or an SBC running Debian Linux using the Python Desktop app (terminal client or GUI), or an Android phone with PSLab app.

Most resources are open source, except apparently the Android app [Update: The Android app source code is in Github]. You’ll find KiCAD schematics, PCB layout, and Gerber files here, the PIC24 MCU firmware in another repository in Github, and we’ve already linked to the Python desktop app source code above. You may also consider purchasing recommended extra components & sensors to make full use of the board.

It seems to me, Android app sources are also available at: https://github.com/fossasia/pslab-android

Too bad they use non-free Microchip toolchains and a PIC:

https://github.com/fossasia/pslab-firmware/blob/master/travis-install-dependencies.sh

And their logic analyzer has too low 2 MSPS, for example the Seeed Quad v4 has 72 MSPS. At that speed, it would be better to simply flash a 1.5EUR bluepill as an oscilloscope:
