Reprap R.U.M.B.A. Electronics Package

R.U.M.B.A. board with (6) Pololu stepper drivers installed.
RUMBA = (R.eprap U.niversal M.ega B.oard with A.llegro driver)

Includes:
(1) RUMBA Basic board (assembled)
(6) Pololu A4988 stepper drivers (assembled)
(6) heatsinks for Pololu drivers
(1) SD card module for RUMBA board
(2) GT2 20 tooth gears
(1) 12v DC fan 40mm
(1) 100k Epcos thermistor (assembled)
(1) Ceramic screwdriver
(1) Basic wiring set (both motors and thermistor wiring)

With this RUMBA and (6) Pololu stepper drivers, you can run up to 3 extruders on your printer! This is a fully integrated board and can be used in substitution of an Arduino 2560 with a RAMPS board mounted, along with the option for the additional extruder.

RUMBA features:
* fully integrated all in one solution
- Arduino 2560-R3 compatible (works with Sprinter, Repetier, Marlin out of the box)
(easy to change/flash firmware for end user)
- ATmega16U2 (with enhanced firmware) for high speed USB serial connection (up to 2MBit)

* UNIVERSAL POWER:
- can be used with 12V-35V for motors / heated bed
- integrated high precision power regulators for:
- 12V (FAN/Light/...)
and
- 5V (ATmega2560/Logic)
- power input selector for ATmega/logic (stand alone or power from USB)

* easy DISPLAY + SD-CARD connector
- RepRapDiscount SmartController compatible pin header on board

* up to 6 motor driver with easy micro stepping setup (micro switches)
- TRIPLE extruder
or
- DUAL Z driver and DUAL extruder
or
- ...

* 5x temperature ADC connectors
- e.g. 3x extruder thermistor + 1x heated bed thermistor + 1x chamber thermistor


* 5x PWM capable power mosfet outputs (3 with voltage selector for MainPower/12V)
- e.g. 3x (MainPower) extruder heater cartridge/power resistor + 1x (12V) fan + 1x (12V) light

* 1x PWM capable power mosfet with extended cooling area for heated bed

* 6x end stop connectors with power supply
- Xmin/Xmax/Ymin/Ymax/Zmin/Zmax
- can be used for mechanical, opto, hall, ... end stops

* screw terminals *and* pin header for easy motor connection
- can be used with existing 4 pin Molex plug on motor cable
- easy to attach cables without plug

* USB connector and pin header
- pin header is useful when mounting in a small box

* Power and ALL unused pins available on EXP-3 feature connector
- +5V and +12V
- 2x ADC
- 2x PWM I/O
- 4x I/O
- I2C

* full JTAG support
- JTAG can be used during full operation (no shared pins)
(easy to develop/debug new or optimized firmware using Atmel Studio)
