CUI32Stem

Postby Markus Gritsch » Wed Jul 27, 2011 3:38 am

Hi,

about a year ago I tweaked the Open Hardware layout of a PIC32 board called "CUI32" to my needs [1]. In agreement with Dan Overholt [2], the original creator of the CUI32, the changes went into SVN, but a new revision was sadly never produced by SparkFun.

Recently, Dan contacted me if I would be interrested in modifying the layout again to include some "twig" connectors used by SeeedStudios GROVE [3] system. I agreed, and the outcome is now called CUI32Stem [4].

3D renderings can be seen attached to this post. I used EagleUp, which Ian recently mentioned in the blog [5]. The setup was very easy, and I can highly recommend it.

SeeedStudio is currently producing a prototype of the board and if everything goes well, they will have the CUI32Stem in their stock relatively soon (or so I do hope) :)

Have fun,
Markus

Nice work Markus,
I hope someday we will have 3D printers printing directly PCB from such 3D representations :p or priting even the components themselves directly on the board :D

I recently purchased a CUI32Stem from SeeedStudios. I am having fun getting it to work with various Grove modules using StickOS. I was able to find schematics for the CUI32Stem but it is not complete. It does not show the two rows of connectors for the signals to the Grove interfaces (the other two rows show up as Power Bus connectors). Is it possible to get the schematic for the board that I purchased from SeeedStudios? I have used the layout files to verify that the Uart Rx and Tx pins on the Grove connectors are the pins that StickOS expects for the UART (RF4 for Rx and RF5 for Tx), but this assumes that the layout file is consistent with the board that I purchased. I would like to build my own shield with some of my own logic, which will include an FPGA and a correct schematic and layout would be very helpful. Please let me know if/how I can obtain these files.
