PoE 802.11af limits

Does anyone know how much current I could draw through an 802.11af PoE board fitted to an Ethermega (including or excluding the mega and its ethernet)?

Re: How to unlock a LeoStick with a hung sketch (and why)

Arduino 1.0.1 seems to compile a bit faster.
I have to do this every time, so far at least. Same story both under Win7-64bit and XP.

Re: Bitten by the offset headers bug

It's not so much that it slipped through the cracks, but was a (much-criticized) design decision by the Arduino designers.

Re: Ndrive driver module, PWM, FET open circuit

"Only drawing an amp or two" - is that the peak, or the average current? For a given voltage, motors draw more current while stalled or spinning slowly, than when spinning fast. If trying to run a motor more slowly off PWM, the "on" part of the cycle will see more current than the constant current o...

Re: Case for EtherTen

I've nearly completed one for EtherMega that has a "with LCD shield" lid option. It would fit an EtherTen with space down the back end. Design should be on Thingiverse soon.
If you don't have access to a 3d printer, we might work something out..

Case for EtherTen

There's a 3d-printable case at http://www.thingiverse.com/thing:26981

I haven't tried it yet..

Re: RepRap printable case for Freetronics EtherTen

I'm designing a case for EtherMega, which AFAIK has the same front-end layout as EtherTen. Will post in this forum when I've tested/adjusted/proven the design.
