@BDub, I checked my connections against the LED I have installed (never looked at the Spark LED data sheet). I used EAGLE to make all the connections so I doubt they got flipped. Here is a link to the Schematic and to the Board . Maybe you will see something else that is obviously wrong (besides that is the first PCB I “layed out” so it isn’t the most well thought out)
Even if I assume the LED is connected backwards, that wouldn’t explain the inability to enter DFU mode. For the DFU connection I was following @kennethlimcp tutorial (which works for my factory Spark Core - even after flashing it from scratch)
