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.
