    Could please upload the open-source design so we can look at it and possibly come up with something that meets your requirements.

    If you can not upload the design then I assuming you got off the web so the website link will also work.

     

    What does this design do?

    Its a brain computer interface. Used the TI ads1299 chip.

    Problem is the rfdrino module is obsolete as well as one of the diode arrays

    So my thought was to

    fix the diode array foot print..

    eliminate the rfdrino and the pic processor.

    add the 40pin header for the raspberry pi ( pi zerow2 has built in bt and wiffi and is a lot faster processor)

    bring the ads1299 spi pins out to the pi 40 pin header.

    Im trying to do it myself but the learning curve is tough

    I can not find the schematic. Can take a screenshot of it and post it here?

    OK got it.

     

    To do what you want to do is going to take a lot of work. For me to make the PCB I will have to redo the schematic in DS. That's going to take a  lot of time, then doing the PCB would also take a lot of time. It will take over 3 weeks and somewhat expensive.

    I have a lot of questions, maybe we should take this e-mail so we do not clutter up this forum.

    There might be someone else who willing go this rework.

    I want to get rid of the rfdrino and the pic processor. Take the spi pins off the ads1299 and bring them to a 40 pin header to plug my raspberry pi zeros into

    As I work on it, it is becoming beyond my skills. The problem is the ground planes and the sheer number of traces that need to be route.

    Sorry
