The new USB Power Shield boards (rev. 2.0) have just arrived from BatchPCB! As always, they were quick, great quality, and they even sent me a few extra! Awesome service.
Version 2.0 has some major revisions since v1.0, including:
Smaller Size – cost is determined by size, so I brought it down to the bare minimum – [...]
A special envelope arrived yesterday from BatchPCB – the envelope containing the prototype board for the USB Power Shield v1.0. Or should I say prototype boards – they were kind enough to produce two, even though I only ordered one. Consider me a happy customer, especially because the boards work.
That’s right, the very first prototype [...]
Things have been quite here lately – but think of it as the lull before the storm! Coming soon to a blog near you:
USB Power Shield Prototype
The PCB has finally been produced and is on the way. Expect to see a fully functional (*fingers crossed*) version in the next few days! If the board is [...]
After toying with the relays and Arduino I found that the diodes weren’t necessary – especially since the relay is latching, and current will be flowing both ways, so putting a diode in each direction would just create a short.
As such, I made some modifications to the board and put it into Gerber files using [...]
I really wanted there to be a complete solution for the Woot-Off lights project that could be almost plug and play for the end user, so today I drew up a schematic and a board for a USB Power Shield for the Arduino. It pops onto the Arduino like any other shield, and by controlling [...]
