Rev 1.3a Assembled 3D Printer Diy Kit integrated RepRap Sanguinololu

Quick Detail:

RepRap Sanguinololu Rev 1.3a assembled
1.High quality
2.100% brand new
3.Competetive price

Description:

Sanguinololu is highly integrated with all the functions that a 3D printer needs. It is of high capacity-price ratio and support Reprap style printer and other CNC devices (Computer numerical control devices). The 4 stepper drivers are completely compatible with A4988 and DRV8825. Sanguinololu adapts developer friendly expansion port supporting I2C,SPI,UART,as well as ADC pins. All 14 expansion pins are reserved to be GPIO as well. Power supply for sanguinololu is also flexible; users can choose ATX-4 power input or the 2pin connector to supply.

Features:

1.support multiple communication configurations :

UART1(RX TX),I2C(SDA SCL),SPI(MOSI MISO SCK),PWM PIN(one),ADC(five)

2.Support multiple power configurations:

Main board supplied by 5mm screw terminal, and optional 4pin ATX connector: 7v-12v

3.Adapts Atmel's ATmega644P - ATmega1284 drop-in compatible. Currently, we use 1284P, the bootloader has been burned before shipping, and users can put it into use after burning the programming code.

4.Adapts FT232RL on-board for USB connectivity, which is an industrial USB-serial chip, ensuring the stability and convenience of installation.

5.Selectable power supply for end stops (5v or12v).

6.With 4 stepper driver on board (Z supports 2 stepper motors)

7.2 N-MOSFETs for extruder/bed, or other peripheral device

8.Supports LCD 2004 module, available for off-line printing.

Version 1.3a - Updated July 21, 2011

Version 1.3a has no software changes - the pin assignments remain the same and your 1.2+ compatible firmware should work here fine. The hardware changes:

• Removed the Molex HDD connector in favor of using the voltage regulator - some power supplies give a dirty 5V signal when there is no motherboard load, so its better to just use the power supply's ATX+4 connector and the 5V voltage regulator.
• Added a jumper to enable/disable USB auto-reset. This way if you're printing from an SD card, you can disconnect your USB and reconnect it without interrupting a print.
• R7 and R8 are now 100k pull-up resistors that are on the stepper-enable lines. This ensures the stepper motors stay disabled and don't move while uploading new firmware, rebooting, etc. The current limiting resistors for the FTDI are gone.
• There is an extra Z-motor header for Prusa Mendel.
