Can you tell us the chip number so we can see specs, etc ?
Any hope that the board could be configured to drive a transistor or FET for use with higher current stuff (LED strip? ETC)
Non-Isolated output I assume?
DMX through or output?
Input Output Connectors?
I'd be up for maybe 20-50 depending on how long the pay date is from now. I'll also offer to be a US ship point for anybody over here to keep shipping down for the US folks.
since no price is locked in, Im willing to go for $100 bucks worth.
that's about 33 of them according to my calculator
Thanks for this MPH - I'm sure this will become the standard for DIY. We would like a lot of them. Chat with you about how many!
Sounds awesome at this point. Once you've got a working design I may well go for a fifty or hundred of these myself. Big props for giving back to the blinky blinky community MPH.
Count me in for 20 please Andrew
Sounds fab, mph ... but could you explain why 4 channels, pls ???
Is the CC part of the IC linear? What I mean is: is it a linear constant current source that has pwm applied to it for dimming?
Also, does it have a Vo range that needs to be adhered to? That might be a problem. It would mean you'd need to be very careful with the number of LEDs and the supply voltage.
eg. A single red LED and a 12V supply would leave Vo @ 11.2V and potentially dissipating way too much. That's one drawback CC chips can have.
Put me down for 20 thanks.
I would be interested in 40 - 50 what ever works out come order time.
I'll take 50 please. Great project - thanks
Edit: Just upped to 50 from 20, as I just thought of a few new uses for them
i'd be interested in 50 , maybe more.
OK, sounds like I'd be mad to pass this one up. 20 boards for me please!
100 for me
