[Discontinued] Sanguinololu Rev. 1.3 Atmega1284p + A4988 + Endstop 3D Printer Kit For RepRap

Description:

This is the new SainSmart Sanguinololu Starter Kit, developed specially for those beginners who are interested in 3D printer.  You will have a complete set of Sainsmart's most common and useful electronic components. What's more. We will offer you a detailed tutorials including project introduction and their source codes.You may learn about Sainsmart through using these basic projects.

SainSmart Rev. 1.3 Atmega1284p Reprap 3D Printer For Sanguinololu
The board is designed to be flexible in the user's power source availability, allowing for an ATX power supply to power the board, or the user can choose to install the voltage regulator kit for use with any power supply 7V-30V.The board features a developer friendly expansion port supporting I2C, SPI, UART, as well as a few ADC pins. All 14 expansion pins can be used as GPIO as well.

Features
1.Sanguinololu IC : Atmega1284p2.Supports multiple communication configurations--2 thermistor connectors with circuitry --2 N-MOSFETs for extruder/bed, or whatever --Selectable 12v(or supply voltage)/5v endstop voltage --Edge connectors enabling right-angle connections --13 Extra pins available for expansion and development - 6 analog and 8 digital, with the following capabilities, and SD CARD SUPPORT 
3. Supports multiple power configurations -- Logic & Motors supplied by ATX power supply (needs molex harddrive connector, and optional 4pin atx connector for additional 12v/supply voltage) -- Logic supplied by USB bus ,optional on-board voltage regulator (molex harddrive connector cannot be installed at the same time)-- Motors supplied by 5mm screw terminal 7-35V  
4.Small design - board is 100mm x 50mm (4" x 2") - barely an inch longer than a business card! 5.Sanguino clone, Atmel's ATmega644P - ATmega1284 drop-in compatible!! 6.UART1 (RX and TX) 7. I2C (SDA and SCL) 8.SPI (MOSI, MISO, SCK) 9. PWM pin (1)10.Analog I/O (5)

Power Connection
The 12V connection to the board needs to be able to carry sufficient current to run 5 motors, the hotend and a heated bed (if you choose to use one) through the electronics. This kit includes the screw terminal connection option and the 7805 5 volt regulater option.Many builders have had problems using PC power supplies, so we recommend using a true 12volt, 25-35 amp power supply and the screw terminals.

Sainsmart A4988 driver
This product is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

SainSmart Mechanical Endstop
SainSmart Mechanical Endstop perfect for any 3D printer (Including Prusa Mendel i2, Prusa i3, MendelMax, Rostock etc...) also for use on CNC machines and other electronic applications.

Notes

• The Sanguinololu design is excellent but if you are going to run a heat bed the traces on the Sanguinololu board are NOT sufficient to carry the current required to operate the heat bed. 
• All SminSmart board for Sanguinololu kits we sold have been tested on the 3D printer machine by our engineers,and it works perfect well.Any technology problem,Please feel free to contact us.
