RUMBA32 is a 32-bit version of the RUMBA 3D Printer control board. RUMBA32 is derived from the Aus3D RUMBA design, which is an overhauled version of the original RUMBA.

RUMBA32 combines the improved RUMBA design with a powerful 32-bit STM32F446 microcontroller.

In keeping with the original RUMBA design, RUMBA32 is fully open source. RUMBA32 boards are available for sale in the Aus3D shop.

Instructions for configuring and uploading Marlin using PlatformIO can be found on the Marlin - Build and Upload (PlatformIO) wiki page.

RUMBA32 is currently supported by the following firmware:

• MK4duo (support in v4.4.0)
• Marlin 2.0 (support in bugfix-2.0.x)
• Repetier-Firmware V2 (support in dev2)

RUMBA32 is fully open source, and may be freely modified or changed by anyone, provided they maintain the license it is released under. The design is free to use for any purpose, including commercial uses. RUMBA32 maintains the GPLv2 license of the original RUMBA board.
