No IC’s or capacitors to solder, only 2 USB SMD ports
Data pins on the output side are shorted ensuring 1A charge rate to device, and still acts as a USB Wrapper and won’t let data pass thru it.
You can either make a charge only cable by cutting it open, splicing the data pins together shorting them, then heatshrinking it closed, or plug a regular data enabled USB cable into this then plug it in.
DCP Enumerator w/ IC and capacitor (up to 10W 2A charge signature) thread
Sorry for the lousy picture
Top board is the DCP Enumerator w/ IC and capacitor, Bottom board is component less, only USB jacks, data pins are shorted on output side (will only be able to charge at up to 5W or 1A max [bottom prototype also had a via “stop” problem and the via’s weren’t connected to the ground plane so no current flow, I had to jumper the pins, release board has the fix on it)
Either way, both of these act as a USB wrapper and will prevent juice jacking or allowing data to flow to any unknown USB port
are these assemble-it-yourself, with some (or all?) of the parts available as a bundle somewhere?
I’m not quite yet to the “get the board from Oshpark and build it” stage, though I guess that’s where we’re all headed.
