Features
Logic
Arduino MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware
Crystals for both usb and mcu (timing accurate to 10ppm)
4 Thermistor jacks
All extra pins broken out on both processors (allows using the 32u2 for LUFA AVR programmer, etc.)
2 channel SDRAMPS compatible SPI breakout

Motor Drivers
5 A4982 1/16th microstep motor drivers (A4984 1/8th prior to v1.1) (2 connectors on Z for Prusa Mendel and other dual Z printer designs)
Digital Trimpot for stepper current control
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
Extra driver ports broke out for up to 3 additional drivers (some of the motor extension pins are shared with max endstop and a pin allocated for SPI-SS extensions)
PWM DC outputs (Extruders, Fans, Etc.)

6 outputs
Low resistance mosfets for cool running
Indicator led for each channel

Power
Three independent power rails for flexible input power configurations
Heated Bed, 15A 12-24V (version earlier than 1.1 limted to 14A 16V due to fuse rating, see rambo_development for hacks)
Extruders and fans, 5A 12-24V (fuse can be exchanged for up to 10A capacity) 10V-26V input voltage
Motors, 5A 12-24V (fuse can be exchanged for up to 10A capacity) 10V-26V input voltage
Built in SMPS for 5V generation

PCB
4 layer
2oz copper on all layers
High quality, High temperature FR4-TG130 PCB
Gold ENIG finishing

Powering RAMBo
Different versions of RAMBo require different power rails connected to power the logic. Please see the page for your board:
See RAMBo v1.1 for information applicable to version 1.0 through 1.1.
See RAMBo v1.2 for information applicable to version 1.2.

USB Driver
Windows requires a driver to communicate with RAMBo. Download this file File:RAMBo USBdriver.zip and unzip it into a known location on your computer. In windows 7, plug in your RAMBo board, and let windows fail to find the driver. Then, go to the start menu, right click on computer and click properties. On the left, click on Device Manager. Scroll down to Unknown Devices, and right click on RAMBo. Choose Update driver. CLick on "Browse my computer for driver software", then click on "Let me pick from a list of device drivers on my computer", then click the button for "Have Disk" and then click browse and point it to the file you downloaded above.
Linux and Mac use the built in CDC driver. RAMBo should show as a option in your 3D printer control interface (/dev/ttyACM0, etc.).
