BAM&DICE is now available


We made it: The first charge of our universal and modular controller is ready. BAM&DICE is now available in our webshop.



The main features we looked for in our development were: simplicity, high performance and superior flexibility. The BAM shield, together with the various DICE-Boards offers a highly flexible interface to implement many different applications. The design is fully Open Source, and our thanks go to the RepRap community, which laid the foundation for this development with the RAMPS board.

With our Indiegogo campaign (see blog entry and campaign) we found some financial support and we want to give our biggest thanks to all our supporters and interested parties which spread our ideas and made pre-orders.

Many thanks!

The BAM-Shield

The BAM shield is the interface between an Arduino Mega 1280 or Arduino Mega 2560 and the DICE boards. Five slots allow all combinations of the different available DICE boards. The four layer pcb offers up to about 800W outrageous power for nearly any tinker project. All features known from the RAMPS board, like interface to SD cards or displays, are also supported with the BAM shield.



The DICE-Boards

All DICE boards are compatible with the interface of the BAM shield. Various boards are available, from stepper motor drivers to IO expanders over temperature measurement boards to valve control modules. Please take a look at our webshop or click on the pictures below to get a detailed description.

Stepper motor drivers:

 DICE-STK-web DICE-L6470-web  DICE-TMC-web
Stepper motor driver
with STK682-010-E
SPI stepper motor driver
with L6470PD
SPI stepper motor driver
with TMC2660

Various modules:

DICE-9555-web DICE-TC-web


Digital IO expander
with PCA9555PW
Temperature measurement
with MAX318555
for Thermocouples (Type K)
Valve-/ Relays controller
with VN808CM-E

With the DICE adapter, every DICE board can be simply tested and used on a breadboard.




The BAM shield together with four DICE-STK modules and an Arduino Mega 1280 or Arduino Mega 2560 offers everything you need to control a 3d printer. Supply voltages of up to 32V and maximum phase currents of 2.85A for stepper drivers offers ample room for big NEMA23 stepper motors and big machines. The fifth DICE slot can be used by any of the other extension boards above.


The future of BAM&DICE

The base concept of the PCI-E slot with it's 36 pins allows many different development possibilities and we hope to explore many of them. We hope to spread this connector and think it would allow some standardization for many different use cases. For this, we offer all schematics, eagle files and BOM lists for all modules under the Open Hardware license CERN OHL V.1.2 free of charge to everyone. For our next development steps we plan to target the Rasberry Pi and the Beagle Board to be able to offer multi functional systems based on linux. Also we plan to extend our program of DICE boards to communication, high-power LEDs, DC motors and many more.
