Smoothie Board 5XC - R v1.1

Product Description

The same as the smoothie board 5XC with 1 A voltage regulator on board

The New ! 1.1 version

– upgraded stepper drivers to A5984 with 32x microstepping

-added a solder jumper (JP36) for MS3 on new A5984 drivers

– changed the current limiting resistors (R78, R65-R68, R84-R85) for VBB powered LEDs to 8.2K

– added an electrolytic capacitor (C84) to the 5V power system

– moved the electrolytic capacitor (C63) for the 5x mosfet set and increased its footprint size

– added flyback diodes (D7-D9) to small mosfet outputs to protect from inductive loads like small fans

SmoothieBoard is an Open Source Hardware CNC controller board based on the LPC 1769 or LPC1768 Cortex-M3 chip.

32bits ARM-Cortex M3 microcontroller, running at 120Mhz
Integrated 4GB micro-SD card
Easy configuration by editing a file on the micro-SD card
Ethernet support, presenting a Web interface, and a Telnet interface
Direct access to the micro-SD card when connected to a computer via USB
Concurrent acces via serial using host software, on the same USB cable
Digital current control of stepper motor drivers
More precise and higher speed movement
More correct and longer-ahead prediction of acceleration and movement
Multiple arm solutions ( cartesian, delta, h-bot, etc … )
Hostless usage possible with a control panel
Good heatsinking, allowing full use of the stepper drivers potential
Many configuration options
SPI, I2C and serial port, free GPIO pins available for extension
Can be easily interfaced with external drivers for use with more powerful stepper motors
Can control a laser tube for laser cutting
Can control a spindle and other accesories for a CNC mill.
