Minitronics v1.1 - Controller board
Product description
Compact single-board 3D printer controller with stepper drivers included on-board
Minitronics is our answer for the low-end 3D printer range. It's designed to be an easy to use, compact and smart solution to fit 90% of the 3D-printers. Unlike it's bigger brothers Megatronics and Ultratronics, which target at the high-end range, the Minitronics is your best choice for an affordable 3D printer controller but still with high quality components.
The board has a powerful Atmega1281 processor with 128 KB memory, running at 16Mhz and can be connected to a PC using a normal USB cable. The board is compatible with Arduino and will therefor be easily programmed from the Modified Arduino IDE, which you can download in our software downloads section. We provide firmware that's ready to run with the board, but you need to adjust the settings or your machine.
Major features
Atmega1281
Powerful Atmega1281 processor with 128 KB memory, running at 16Mhz
Small design
Only 94x57x18mm in size
Thermistors
Two thermistors can be connected
Four MOSFETs
The board has 3 regular MOSFETs (for extruders etc) and one MOSFET for the heated bed (10A) to support
many needs.
Up to 5 stepper drivers with 1/32 step
The Minitronics has four on board stepper drivers. A fifth can be connected externally, using
our External stepper driver board.
Other features
- USB 2.0 Full Speed compatible
- Auto reset can be disabled by removing a jumper
- The board can be powered from 12V (12V MAX), by setting a jumper
- 12V has a diode to protect against reverse polarization
- The 5V line is protected by a 500mA resettable fuse
- Four layer high quality PCB board
