Has anyone used these? They could decrease the profile size of a PIR style sensor. Also 3.3V. Thoughts?

I have it. My first 3d printer so I can't compare. I hooked it up to a octoprint pi setup. I really like it. I have already changed the hot end for a volcano setup.

Hi @mtiutiu - Did you ever get a chance to make a BOM? Most of the one @tonnerre33 one makes sense but I only bought two boards so being a little cautious :-)

Thanks!

@sundberg84 It was your project that inspired me :-) - The electronics part etc is not the hard part IMHO on these projects - it is the WAF and how tidy I can have them in the house. Hence I was looking for a box that I knew I could stick a screen and arduino in and not have to worry about it. Thanks for all the work!

Thanks @mfalkvidd !

Any BOM? :-)
I still have these PCBs and want to finish em. Can't source a crystal/resonator of about 5x4 mm.

I am going to try out http://ie.farnell.com/stmicroelectronics/m95128-wmn6p/serial-eeprom-128kbit-10mhz-soic/dp/9755870

Will report back.
