We won't be able to ship any order until September 20th, 2021

Some weeks ago we finished moving our warehouse to Tortosa (Tarragona, Spain). We worked hard to open as soon as possible. We had to get the place ready for the products, install the laser, our saws, etc... We finally opened the store again but now we need some holidays.

We will be back on September 20th, 2021, so we will ship all the orders that same date.

The BIQU-RUMBA control card for 3D printers uses the ATmega2560 chips as the main control chip, the same chip found in the electronic board of Arduino Atmega 2560 and an ATmega16u2. One of the best advantages of having this product is that we can connect up to three extruders and print in three different colors.


• It has 6 available inputs to install the A4988 2A Pololu drivers, DRV8825 3A or the TMC2100 for the stepper motors.

• It has five input interfaces for measure temperature: three for extruders, one for the heated bed and one for environment.

• It has five PWM (Pulse-width modulation) outputs: three for heating the extruders, one for the heated bed and one for lighting.

• Also the board has six inputs: Xmin/Xmax/Ymin/Ymax/Zmin/Zmax, where we can install the endstops.

• Supporting JTAG makes it possible to conduct software development.

To install this product, we need the firmware, based on Marlin.

Output voltage: 12V ~ 35V.

This product includes a 22 cm long USB cable.
