Ultimachine originally set the bar when they created a solution to eliminate six boards into one - the RAMBo 1.3. But now, they have built something even stronger - the RAMBo mini. The RAMBo mini contains the highest quality components and new cooling features. If you are looking for the best board for your buck, look no further!

Ultimachine has stepped it up since their RAMBo 1.3. The RAMBo Mini contains complete revamped cooling for stepper drivers that are supported by a four layered PCB area. This guarantees your drivers will never fail! The mini also allows one to regulate the motor current and microstepping straight from the firmware.
Another key feature this board has to offer is its petite size so that it can easily be hidden within a machine.
This board kit comes with connectors, endstop switches and precrimped cables.
Features:
Arduino MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware
Crystals for both usb and mcu (timing accurate to 10ppm)
3 Thermistor jacks
Motor Drivers
4 A4982 1/16th microstep motor drivers(2 connectors on Z for Prusa Mendel and other dual Z printer designs)
PWM Outputs for (XY), Z, E0 stepper current control instead of digital trimpot.
Current limit on driver IC VCC to prevent permanent latchup
Microstep mode configured by MCU through firmware (no jumpers needed)
Test points for driver control signals
Step and Direction pins are on their own ports for synchronous movement capability
PWM DC outputs (Extruders, Fans, Etc.)
4 outputs (1 Extruder, 1 BED, 2 low power (fan,etc)
