I was in need for a sequencer. Then I found this module by Extralife. It’s a nice step sequencer that I use a lot. Maybe also because at this moment it’s the only sequencer I have in my rack. I build two of these. You can but this module build but the files to DIY are available on Github also. As I figured I didn’t need more then two I traded the spare pcb’s and panel for other pcb’s. I still have to figure out all the function cause I think it can do more then I currently use it for.
Difficulty to build: Hard, Just because of the W25Q80DV chip that’s pretty small.
