HS101 oscilloscope

A very simple oscilloscope based on STM32F103 MCU that anyone could build designed by Martin Loren.

I designed a small pcb that sits on top of a STM32F103 module (blue pill). It’s the HS101 version and I used a 3.5mm female jack as the probe input.

There are various versions of this project you could build. More info and instructions here.

This oscilloscope can be used with HScope app for Android.

The firmware can be flashed with STM32 Utils on Android using a USB-TTL Cable or using the source code if you have a programmer.
