New electronics: Minitronics
April 12, 2013 04:23PM
I am glad to announce a new line of electronics: Minitronics. We already have the Megatronics board, which was designed to be a replacement for RAMPS, very advanced and allowing a wide range of uses. The Minitronics is to be a replacement for Sanguinololu. Should be just plug and play and fit 90% of the normal 3D printers.

The electronics will be available within a few weeks. I need some time to finish all documentation. But here are the main features:

- Small design (94 x 57mm)
- Support for 5 stepper motors (4 stepper drivers on board, 1 externally)
- 3 end stops
- 2 thermistors
- 4 MOSFETS (3x normal, 1x heavy)
- Atmega 1281, with 128K memory available running at 16Mhz
- Compatible with Arduino

Hi brupje,
Sounds really interesting for your minitronics. Does this means mini electronics? Anyway, those features is quite attractive. Especially the small design feature. Surely people will find great interest with your minitronics stores.

64.99 excl VAT, so somewhat cheaper then our sanguinololu basic kit

Boards will be available somewhere this week

Pretty neat little unit.

Would definitely make it easier on the people that aren't familiar with electronics to get into small DIY 3D Printer.

I hope there is some decent protections in those stepper drivers. I'd hate to see someone blow one, and not be able to easily replace it.

These stepper drivers can handle some pretty abuse, but if you want, you can break anything winking smiley

hey bart!

any chance you can plug in an lcd/sd card into your board?

Not directly, it's a ver slim board. Megatronics has the advanced features:-)

Nice work!!! What program are you using to open the PCB file. All programs I use gives me error. :-(

Hi brupje,

i've already ordered one from reprapworld! But i'm wondering what load the drivers can handle? There is no Issue in your datasheet. Can it drive Nema 17 40Ncm 2.5A?
