We begin the tour of Iris' guts by looking at the new 4-in-1 ESC/Power Module. Each ESC is rated at 20amps capacity and is running the SImonK firmware for enhanced response and stability. The onboard Power Module provides regulated power to the flight control board, in addition to voltage and current monitoring.
An aluminum heatsink is attached to the power handling transistors
This 4-in-1 represents an elimination of 110 grams when compared to four individual ESCs, Power Module, and Power Distribution Board.
Comments
Given they're 20A ESC's i'm guessing 3S and possibly 4S.
what voltage? 3s,4s,5s,6s?
Just as a point of comparison, the Hobbywing Quattro 25A is 62.8g with the big wires removed.
Gary,
I'm not sure what the cost will be -- the components are not cheap, but it's not a big deal to replace. This thing is easily accessible after removing the bottom shell.
Alex,
I thought the video would cool and Vine-esque, but it just made people angry. I'll put together a longer version and re-post it.
titeuf007,
The 4-in-1 weighs 58.7g with the heatsink.
@Shyam Balasubramanian
That's not necessarily the case. The 30A Afro ESC's from Hobbyking are $13 and were designed and made with input from timecop and SimonK themselves. So, lets not get ahead of ourselves.
Each 20Amp ESC's with Simon K fw, costs 25$ or so. With the extra additions to this board (like filtering & heatsinks), one can expect it to be somwhere around 100$! IMHO..
Good point John. The Hobbywing battery connection pads are positively riddled with vias. I wasn't sure what that was about until you mentioned it here. Makes sense.
@Earl,
Under how much? Have you been somkin' that wild weed again?:-)

The AMP and voltage monitoring is a big plus. HOW MUCH!
