Iris details: #1 The 4-1 ESC/Power Module

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.

How much do they cost to replace Josh and is it a mission?

Very nice!  I love my Quattro ESC's, so I think these 4-in-1's are great.  I see individual processors with the programming pads broken out in a row.  Nice.

That is some high quality goods right there. I am wondering how much it would cost to replace as well.

Nice design and the heat-sink should reduce it's AC EMF substantially too.

I think a lot of us would like to see this as an off the shelf part if possible.

Sure we can get the Hobby King or Hobby Wing ones, but we'd rather buy from you guys.

I'll bet you can guess which part I'm waiting for you to show us!

Ah, I see that hidden on the bottom is the 4 channel PWM reciever!  Meaning I could totally stack up two of these boards to power a sufficiently small octo or X8.

Stephen, yep, a micro Octo would be neat.

Nice design!

Some questions:

1) Is this only valid for 20Amps OR more current?

2) What would be its individual unit cost?

Subbed!

Comment by titeuf007 on August 21, 2013 at 1:02pm

the good question is what is the weight for this 4-1 units?

and what will be the price?because if it cost 3 times more actual 4 classic esc it s not a good option.

A 4-in-1 + PM factory delivered with SimonK firmware is a very nice deal indeed.

One suggestion, based on the pictures shown. I would beef up the solder pads (especially the power inputs) with some vias to thermal sink the pads and prevent accidentally peeling the pads of the board if the cables are pulled.
