Hi all,
Can anyone point me to a source that has authentic Digisparks in stock?
I'm working on a project right now, using a Digispark as a dev board. I'd like to use a real one, but Digistump is understandably a little busy with other ventures at the moment.
I purchased a clone on eBay - One of the shoddy rev3 boards. I can't get any code to upload - The unit does have the Micronucleus bootloader installed (v1.6/1.06), and it enumerates properly as a USB device (I believe). Output from USBDeviceTreeViewer:

>> Micronucleus done. Thank you!
However this doesn't have any appreciable affect on the board itself - The default blink sketch is still on the board.
I've also tried to update the firmware via Micronucleus.exe, similar output to above, but no change in version number.
I switched out the USB protection diode (D3) on the board after finding the thread that covers that, no change.
Any ideas? My fall back to to switch development over to a modified Adafruit Trinket (I would need to reflash it w/ Micronucleus and disable reset functionality because I need every I/O pin for this application). That's a cludgy solution, however. The Digispark is preferable, because it can be soldered directly to the prototype PCB and installed in the enclosure I've designed. I might be able to cram a green-wire connected Trinket in there, but it's not ideal.
