RAMBo mini is 3D printer motherboard with best bang for a buck. We sell only original manufactured by Ultimachine from USA. This ensures highest quality components including Molex connectors. That means you don't have to worry about connectors melting or worse burning. This board doesn't even need active cooling thanks to it's advanced layout, unless it is mounted in enclosed box.

It is an evolution of old good combo RAMPS + Arduino. All the components are place on one simple board instead of 6 interconnected ones.
This board remains Arduino compatible so you can use Arduino software for easy firmware upgrades!
RAMBo mini has a complete reworked cooling of the stepper driver chips. It doesn't use removable Pololu styled boards like it's older brother RAMPS. Driver chips are cooled by the whole 4 layer PCB area and thanks to this they will never fail!
It allows you to control the motor current and microstepping directly from the firmware. That is great feature if the board is hidden and you cant access small trimpots to tweak the current settings.
Board is supplied with preflashed firmware for our Prusa i3 3D printer.
No customer reviews for the moment.
