CompuLab UCM-iMX8M-Mini is a Stamp Size i.MX 8M Mini SoM

We’ve recently written about several new hardware platforms based on the latest NXP i.MX 8M Mini processor family including Nitrogen8M_Mini SBC and F&S Elektronik PicoCore MX8MM SoM. Thanks to a new 14-nm process, the new family has the advantage of consuming less power, and the Cortex-A53 cores can run at a higher frequency. They should cost less as well thanks to cost-saving measures like the adoption of a 1080p video decoder instead of a 4K decoder found in the older NXP i.MX 8M family.

CompuLab has now launched their own NXP i.MX 8M Mini SoM with UCM-iMX8M-Mini module that’s about the size of a largish stamp (38 x 28 mm) suitable for portable and space constrained applications such as professional handheld devices, wearable healthcare monitors and medical devices, autonomous drones with visual object recognition, or portable instrumentation equipment with advanced HMI.

I wonder what applications these things actually turn up in. $54 sounds pretty expensive for something you’re going to mass produce.

Are you serious? $54 sounds like a steal.

Yes. I was literally asking hence writing a question and hitting the “post comment” button.
What sort of product do you use a single part that costs $54 in? CNC machinery? If $54 is a steal
what would you integrate this into? Keep in mind you need to buy $54000 worth of parts to get
that price.

There’s a lot more in the world than cheap consumer applications.
For professional use, a well documented and supported product with a long time availability will save a lot of money compared to a cheap, flaky product with no support.

If you’re selling something for $200 your BoM needs to be under $50 really. So what “professional” stuff does something like this get used in? I wasn’t doubting that these things do get used in something. I’m more interested in what sort of product makes it cost efficient to use. My first guess would have been extremely low volume stuff but it looks like it’s a minimum 1K order.

A minimum of 1K is nothing for most markets. If you don’t plan to sell 1K of a $200-priced product (your pricepoint, not mine), you’re a joker.

As per your question — that thing is a perfect candidate for signage and billboards.

>A minimum of 1K is nothing for most markets. 1K is nothing for low cost high volume stuff. Something based around a single component that costs $54 wouldn’t be in that category I wouldn’t have thought hence asking. >If you don’t plan to sell 1K of a $200-priced product >(your pricepoint, not mine), you’re a joker. Have a guess why I picked that price point. There’s a good reason. It’s weird how you’d be a joker for shipping in low volumes but not a joker for using something that is directly marketed at the low volume market. You would use… Read more »

@ £599 a phone, maybe these? ” While Purism was considering a switch to the i.MXM8 Mini, NXP pushed out a software update for the i.MX8M Quad which resolved the issues, so that’s the chip that will be used for the Librem 5. With that in mind, here’s the final run-down of the specs for this smartphone: 5.5 inch to 5.7 inch HD display NXP i.MX8M Quad processor 32GB of eMMC storage + microSD card reader Gemalto PLS8 3G/4GB modem (on a replaceable M.2 card) TESEO LIF3 multiconstellation GNSS/GPS receiver 9-axis motion sensor Front and rear cameras (specs TBD) Vibration… Read more »

It’s obvious you’re wrong, since there are quite a few companies (not just CompuLab) that have been making a living for decades selling SOMs that cost >$50. There’s a world outside of your imagination; a couple markets I know a bit about include medical and industrial. I’ll give you an example of industrial thinking: I spec gold connectors on our machines, because if using gold instead of tin saves one service call, the gold connectors have been worth it (either in avoiding warranty costs or avoiding costs to our reputation). Long term availability also matters; we have machines that are… Read more »

Typical response in the CNX-software comments on any SOC/MCU that is priced more than an ESP8266 or AllWinner SOC : “oh my God! $54 so expensive!! I can get similar AllWinner SOC for $2-5”.

Ok fine go use your cheap and poorly documented AllWinner SOC and leave us alone. Some of us will gladly buy the $54 for the god damn module.

> “oh my God! $54 so expensive!! I can get similar AllWinner SOC for $2-5”. That’s not what I wrote at all. $54 is a lot of money for a single component in a BoM. Considering the audience of this site I thought someone might actually be able to point out where these sort of things are cost effective. There again maybe I should have expected a bunch of people that don’t know but wanted to chime in with their big boy thoughts regardless. >poorly documented AllWinner SOC and leave us alone. Who is “us”? Anyhow it’s weird you bring… Read more »

FYI: According to their pricing table the basic module (1GB of RAM, 4GB of emmc, no wifi etc) is $54 * 2.5 (single unit pricing). That’s $135. Add wifi and 2GB of RAM and you’re looking at ~$200 a pop. Maybe $200 a pop is ok for some super special industrial machine but if you want the industrial temp tested version that’s another $150 on top.

So I’ll be interested to know what you’re using your 1000s of modules in or what you’re building that would make these worth using considering the cost.

WTF? 54$ Way too much. The combination sounds interesting though. Combining a M core and A core. You could wakeup the A core when some event happens.
