Intro

The RAMPS Interface Board (RIB) is designed to sit between Due and RAMPS to perform level-shifting, and any other needed functions.

Source Files

Source files are hosted at github. Schematic for v0.1

Version 0.1

Status

A prototype has been built, but there are some major issues:

  • gate drivers are not suitable
  • The surface mount connectors are quite expensive

This project has been shelved in favour of RAMPS-FD which is compatible with Due and Mega, and has more features than RAMPS and can take advantage of the increased performance of the Due.

Features

  • 3.3V/5V level translations for endstops and UART TX/RX
  • gate drivers for RAMPS MOSFETs

Errors

  • The analog inputs need to be routed to different pins on the Due, as it has less analog channels than Mega (not sure this is correct!)
