Has anyone here had experience using this hardware with a Linux-based machine yet? I own a Jetson Nano and was interested to see if anyone had success with it. The developer board has a socket for this that is normally used for a wifi card.
Given this quote from the docs:
The mating connector is a an M.2 (NGFF) type 4. Note that there are several different key configurations for the M.2, and type 4 is different than is commonly used on SSDs.
I’m assuming that there might be a physical compatibility issues using it in your Jetson Nano.
Was afraid of that, although it’s certainly not a deal-breaker. Sure good to know all of the gotcha’s, and sure do appreciate the heads-up, TrikkStar. Thanks.
I will say that the SoM Eval Board is basically everything you’d need to start tinkering with the SoMs.
Nvidia Jetson Nano and Xavier NX carrier boards are M.2 A card PIN LOC 8-15.
It appears the Particle B Series is a M.2 E card. PIN LOC 24-31
I don’t know of M.2 cards with ‘type’ numbers just KEY positions with some having 1 slot and other having more as in Intel® Dual Band Wireless-AC 8265 M.2 A-E
DELL explains nicely: https://dell.to/2SXOUOH
In the B series docs it says it is a TE 2199230-4 connector which is the same connector used on the Nvidia carrier board… BUT https://docs.particle.io/datasheets/cellular/b-series-datasheet/
When you look at this you can see the ‘slot’ is shown as a E key on the PCB yet they show the A Key with the TE connector? That and the image https://docs.particle.io/assets/images/b-series/b-series-top.png of the B Series PCB shows it is an E KEY.
It is an E key, but the more fundamental limitation is the pinout is specific to Particle SoM modules. It’s not designed to fit into an existing board that’s not designed specifically to connect to a Particle SoM. It’s completely different than the M.2 SATA and M.2 NVMe, for example.
