YOUYUE 858D+ hotair station — reverse engineering #5

The lack of an ISP connector on this board has given me a lot of grief. This little adapter board will solve that problem once and for all. It also provides a couple of through-hole pads for potentially adding some more stuff. Clearance distances to the high-voltage parts should still be tolerable.


You can find the gerber files on the projects page.

    Nice! Did you etch the board yourself? If so how did you do the white text and what solder mask did you use?

    Wow, thats like 15 eurocent per square cm of double layer pcb, shipped from usa…

    Your Code works absolute perfect

    Thanks for your work

    I just ordered the board from OSH park. Unfortunately I neither find the values for C1 und C2 anywhere nor can I find a source for the soldering pins that you have used.
    Could you add that information?

    Thanks a lot!

      The values are in the schematic file (PDF), which you may have missed. I’ve renamed it to make it stick out more.

      I’ve added a digikey order number which _may_ work. Best to check the dimensions in the datasheet.

      Am besten bekommt man die Sockel von MPE/Garry (siehe Docs Ordner) bei Reichelt.
