Getting ready for the CM3?

[W. H. Heydt]

Allied (US subsidiary of RS) for the first time I've seen is discounting the price of the CM1 Dev Kit. They have it down to $75, but none are available to ship. The page is here: http://www.alliedelec.com/raspberry-pi- ... /70378477/ The CM1 itself is still $40 and they saw that they can ship some 3700 of them "in 10 days" (that last being a little weird). The prices on the RS Export site are better (it's showing me $67.50--which may include VAT, it was lower a couple of months ago--and $26.31, respectively).

In any case, my current expectation is for the CM3 and CM3L to show up in a couple of months.

In the UK the CM1 Kit is available, 1,300+ in stock

I was under the impression the Carrier Board could be modified to accept a CM3?

Ordering from RS in the UK is a bit tricky when one is in the US. They want to redirect to Allied and prices (on the few things I've looked at) are frequently rather different--or even not available at all. One has to go through the "RS Export" site to make it work, and even then one has to decline being sent to the US site.

First I've heard about modifications. There are two (known so far) differences between the two CMIO boards. The first is the way power is set up to handle the '2837 requirements. I suppose one might reasonably be able to modify the CMIO1 to work with the CM3 board. The other is that the CMIO3 board includes a microSD holder so that one can work with the CM3L. I don't think a CMIO1 board could be modified to handle that.

The CMIO Rev 1.2 is easily modified to boost the Vbat core supply, as above.

Adding a uSD socket should be possible too, but requiring finer soldering skills.

@WHH I ran some tests on my WD Labs Mediastick. The Vbat line is 3V3 there, but it appears it is beefy enough for the CM3 as I am able to draw around 4000mW from it. Chances are your WD SATA adapter enjoys the same buck regulator (there are two separate little square chips, one each for 3V3 & 1V8).

I did say "probably".

That's what I thought, too.

Interesting. That implies that the WD SATA Adapter will also most likely provide enough power for the CM3 (and even better, the CM3L). I will test that once I get my hands on enough equipment to do so. The big bottleneck is still going to be the USB2.0. Relieving that is going to take at least another 2+ years, though.
