#RAMPS ARDUINO SHIELD USB DRIVER FOR MAC MAC OS X#

The max current you require will depend on all your components and the voltage you run them at. Many PSU's overestimate their max current capability.The max current limits will of course be different. Some variants of RAMPS have real fuses in place of the PTC fuses (eg: GRRF RAMPS).It is not recommended to exceed 15V for a standard setup, especially if you've bought your board from a cheaper supplier who may have used lower spec components than are recommended. Most RAMPS boards will happily run at 13.8V or slightly higher with no modification. RAMPS was developed with 12V systems in mind, but it is possible to run it at 24V with various precautions. Standard RAMPS has a 11A PTC fuse that runs the D8 output. This PTC fuse is rated for a max of 30V, however other components on the board are rated for lower voltages, so care should be taken when using any voltage >12V. Standard RAMPS has a 5A PTC fuse that runs the Arduino Mega, the stepper motor drivers, and the D10 and D9 outputs. Option to connect 2 motors to Z for Prusa Mendel.These connectors are gold plated, rated for 3A, very compact, and globally available. Servo style connectors are used to connect to the endstops, motors, and leds.

All the Mosfets are hooked into PWM pins for versatility.

I2C and SPI pins left available for future expansion.

Motor driver boards are on pin header sockets so they can be replaced easily or removed for use in future designs.

Fits 5 motor driver boards (you can find two types on the right).

Heated bed control with additional 11A fuse.

Fused at 5A for additional safety and component protection.

3 mosfets for heater / fan outputs and 3 thermistor circuits.

Expandable to control other accessories.

Version of the Uno is the first in ttl com p. I believe the Arduino USB peripheral cable USB specification rev 2.

It has provisions for the cartesian robot and extruder. Specifications Winchiphead CH340 / CH341 / H元40 driver The Prolific Winchiphead CH340 / CH341 / H元40 Serial Driver for Apple Mac OS X driver is the reliable interface between your CH340 / CH341 / H元40 based cable and your Mac.it's double sided board, but one of layers can easily be replaced with wire-jumpers) that is printable on your RepRap with the etch resist pen method, or home fabbed with toner transfer. Version 1.25 and earlier are "1.5 layer" designed boards (i.e. If you want to etch your own PCB either get version 1.25 or Generation 7 Electronics. As of version 1.3 in order to fit more stuff RAMPS is no longer designed for easy circuit home etching. Version 1.4 uses surface mount capacitors and resistors to further cover edge issue cases.
