#electronics #chumby #reverseengineeing can anyone help me figure out what diode might've been here? another one in the same board with the same footprint reads 3U and in a pinch i could take apart another working chumby but because it involves peeling off glue i would rather not (and i don't think looking at that one would tell me anything)
i believe this diode is keeping the chumby from powering as without it RAW_PWR and GND on the chumbilical read 0V although i can see the input 12V if...
@mavica_again looks like a forward pass diode, give it a shottkey diode good for 1A ?
@mavica_again
Schematic says RSA5M? Is that the same device? Second to last page.

...i measure against EMI_GND instead
i tried briefly sounding off with the continuity meter to tell where this diode goes but i couldn't find anything. i'm happy to take higher resolution pictures and answer questions, unfortunately the daughtercard where this diode is does not have its schematics released unlike the main computer board and there aren't many people left active in the chumby forum
