Introduction
The Mini3dprintercontroller Board is part of Mini3dprintercontroller Electronics. This is the central part of mini3dprinter Electronics. A board with all the features required to run a 3dprinter in a very small board 50 X 50 mm and also including pin headers to plug in driver boards for stepper motors control and LCD and micro SD card reader too. This version has 2 connectors heaters for an extruder and bed, also power for fan, 3 limits and 2 for temperature sensors like thermistors and serial port for the USB-TTL adapter or Bluetooth module.
The Mini3dprintercontroller electronics is a modular, low-cost electronics solution for RepRap and other CNC devices. Using ATMEGA 644p though an ATMEGA 1284 like Sanguinololu or Gen 7 is easily dropped in. Its 3 axes and extruder motors are powered for external drives like Polulus compatible or many others like Mini3dprinterdrives.
The board is designed to be flexible in the user's power supply availability, allowing for an ATX power supply to power the board for 12 volts.
