The RUMBA is an electronic board that combines the functionality of an Arduino with a RAMPS, but with the advantage of utilizing almost all the pins of an Arduino Mega 2560. This allows for an extra space for a driver, which can be used for an additional motor, whether for an extra color, a Z or X axis, up to a maximum of 6 motor outputs.
Methods to increase the capacity of this board:
- Using a Raspberry Pi, it is possible to install Klipper on the RUMBA, making the project faster.
- With the board operating at 12V and an external MOSFET powered at 24V, the bed heats up quickly.
RUMBA (R.eprap U.niversal M.ega B.oard with A.llegro driver). RUMBA is a
feature rich all-in-one electronics solution for Reprap and other CNC
devices.
- It features an onboard ATmega2560. Its six motor outputs are powered by Pololu pin compatible stepper drivers.
- The most notable being a port for use with touchscreens (TFT) controllers.
- The board features a developer friendly expansion port supporting giving access to all unused I/O, ADC and I2C pins.
- This board is designed to be flexible with power sources with 12V.. It's a solid choice for 3D printing and other CNC applications.
- Chip ATMEGA2560 16AU 1738
- Compatible with 12V components: fans, cartridges, heated bed, power supplies
- 8Bits
