I finally got around to finishing the updated version of the CRAMPS board. This version focused on simplifying the design as much as possible, and I really like the end result. It feels much closer to the original RAMPS for the Arduino Mega in spirit than the previous 1.0 version and the RAMPS-FD.
Changes in this version include:
- No fine-pitch surface mount parts, so the board is much easier to hand assemble
- No servo outputs
- SPI expansion header changed to allow use as extra GPIO if needed
- Expansion headers modified to support an additional 3-axis add-on board (the CRAMP3)
While the design is fully open, not everyone wants to build their own boards from scratch. I am working on getting someone to build and sell completed boards, so stay tuned for updates!
UPDATE: 2014.05.12 - The first batch of 20 boards has shipped, now the 0-30 day wait for a "registered air parcel" begins.
