RepRap MeLzi

A compact all-in-one controller board for RepRaps with one extruder head, optimized for mass production.

The point of RepRap is to make itself, of course. But sometimes people just want plug-and-play RepRap electronics so they can concentrate on the other aspects of the machine, or just because they are more software or mechanics oriented than electronics oriented.

Melzi is designed to be a complete set of RepRap electronics that should be very cheap to mass produce. It was originally based on the Arduino Leonardo (Francesco Melzi was Leonardo's pupil).

Specification:

• Mini USB interface
• 4 x A4988 stepper drivers
• 3 x MOSFET drivers for hot end, bed and cooling fan
• Dimensions: 210mm x 50mm x 17mm
