Oscilloscope on a chip !
This is a cool piece of hardware for your projects.
This is a mixed signal oscilloscope with a small OLED display, an integrated waveform generator and a 8 channel logic analyzer combined, everything on a single small DIP module.
Just plug it into a breadboard or put some headers on your PCB and voila.
