Re: Max current from onboard regulator

Thanks guys. Since the 802.3af reg does 1.5A, you could always regulate down a second 5V supply. You'd need to keep them independent, but you could (in theory) drive another ~600mA off that (leaving yourself with 100mA headroom for overhead for the regs to use - which should be a lot less but probab...

Re: Max current from onboard regulator

I should've done some more reading first, the 5v regulator on the etherTen is 800mA, not 1A. So, 800mA - 250mA for the etherTen = 550mA available?

Max current from onboard regulator

Currently I'm stripping down my letterbox setup as I want to add some more LEDs. It's an Etherten + 802.3af PoE combo currently lighting up 5x 10mm RGB LEDs, each using maybe 25mA max. This runs just fine off the etherten's 5V regulator. What I'm wondering is what the max current I can get from the ...

Battery options and USB-PWR

I'm trying to find the best solution for providing power from a battery and am currently thinking that one of the relatively cheap USB phone charger packs would work well. They're a nice regulated 5V supply and have decently large capacities, even when you take a certain amount off for marketing BS....

Missing Serial.write(buf,len)

Not sure if you guys are after bug type reports, but I came across an odd one tonight when trying to use: Serial.write(buf,len) (As documented at: http://arduino.cc/en/Serial/Write) After much toying around, it appears as though this function hasn't been included in the LeoSticks libs. The solution ...
