    Hi folks and enthusiasts!

    After countless days of thrilling anticipation my recently ordered TinyG finally arrived in Germany (32,06 € customs fee, directly forwarded from customs and paid via cash on delivery, so no troubles with customs, if anybody was wondering..)

    Now comes my issue…there is a capacitor mounted to (yes, to) the feet of the SOIC Motor 2 driver. Could it be, that it has fallen down during pick&place operation?

    So I was wondering, what would be an appropriate action? Should I try to desolder it myself and risk damaging the TinyG? I have the feeling, that a retour is not a real option since I belive it must be incredibly complicated with customs and everything, plus…you know….my Shapeoko told me, it wants that upgrade right now!

    Phun aside…any ideas how to deal with this?
    Picture attached shows the capacitor.

    Best regards
    Simon

    Somehow sharing via Google drive did not work, again this should do it.

    It took a bit of staring, but I did find it!
    Yes, indeed it appears that the C29 chip cap is misplaced.
    It is a 0.22uf bypass for a internal voltage on the U4 driver device,
    but is now soldered to pins 7(and maybe 8) and 10 on U3.
    Here is a link to the applicable schematic

    Best approach, connect with Synthetos via this URL

    That interface will provide them with all the info needed and open a direct channel to customer service.

    Thank you, cmcgrath!

    Somehow I mixed up the community and the synthetos itself.
    I contacted them and will keep the post updated, if the outcome is interesting enough.

    Hi cmcgrath,

    I have not heard anything so far. Is that because of the holidays or has the request somehow been lost?

    Best
