As I were developing the RAMPS 1.7 and RAMPS 1.4.4 shields, I discovered that creating LCD add-on boards would be an interesting way to do further testing and/or add easy-connect functionality to these RAMPS shields.


RAMPS 1.7 - LCD-03

Summary

This LCD board accommodates RepRapDiscount LCDs, both Text and Full Graphics versions, via the EXP-1 and EXP-2 ports

Additionally:

  • As the RAMPS 1.7 shield does not have an AUX-2 connector, this LCD board has an AUX-6 connector, which simulates the AUX-2 port, so it becomes possible to connect LCD displays to the RAMPS 1.7 shield, where the LCD is otherwise designed to connect to the AUX-2 port of a standard RAMPS board.
  • The AUX-3+ connector is duplicated on this board, so it easy to connect SPI items, together with a RRD LCD display.
  • On the RRD LCDs there are provisions for the addition of a Stop or Reset button. This option already has a dedicated wire in the EXP-2 port connector. This wire can be directly connected to the Arduino Reset pin or to D45, by setting jumper J2 on the LCD-03 board.

Where to get the RAMPS 1.7 - LCD-03 board

For now you have to download the Gerber files, and upload them to a PCB manufacturer. This is however a very low cost, and simple and very straightforward activity by now (2019).

You can check out DirtyPCB, SeeedStudio, JLCPCB, AllPCB, and more, they all produce good and very useful PCBs.
