Just in case you’ve not checked the website recently - we just announced impCellular, the first industrial grade all-in-one cellular IoT solution.
When I say industrial grade, I really mean it. The impC001 even has ECC on all its memories. This is really solid stuff that you can rely on - and it’s as easy to use as all imps
Great news ! I was waiting for this after discovering some details on the Dev site.
Few practical questions:
do you have a list of supported carriers in the European Union ?
do you intent to stick to the M.2. form factor for future modules ? In itself a good choice but what is your experience on reliability of the connection ? I"m asking because we had to replace a good portion of our IMP001s based (pilot) products with soldered on IMP002s due to random connectivity problems in the SD Card connector.
There are too many carriers to list, but PM with countries and we can provide the details.
We intend to use m2 for the standalone products, yes. M2 is very resilient (designed for permanent-fit of things like SSDs) hence the screw fixing etc. SD is rather more a consumer connector and the quality of the sockets varies hugely.
We have not seen any issues with M2 in the past year.
Are there any plans to have a WiFi module with the same form factor and connector, so that a board could use a cellular or WiFi module interchangeably?
What is the range of the narrowband cellular like - should we expect usability past limits of where normal 3G/4G cell phones work?
