Hi,
I have some questions, and to be open - I did not yet buy your product, and actually what I’m looking for is a product that can be used in agriculture, so it needs to:
- absolutely be able to operate at -20 to +60 C
- absolutely must have a CE mark so it can be sold in EU
- I2C pinout, 2-3 LAN ports
- sim card holder (+3G with GPS module connector)
- be relatively compact
- preferably, 128mb of ram and ability to expand file system to be of about 256 mb size.
The closest thing is Mifi v2 board and it’s very interesting and almost unique at the market at the time of writing this post. I know that it hasn’t got 12C and memory, but does it at least qualify first two requirements? I do know that you said you have tested ar150 for operating temperature, but how about this one?
If AR9331 itself does not have I2C capabilities, would you consider developing similar product based on MTK, like for example - MT7628AN, or MTK7620N (something you already have experience with), or similar . Because, if you do market research, you will find that there does not exist a single compact product that has LAN switch, Linux core, SIM socket, >=128mb ram, I2C, good operating temperature range, CE certificate and a price in the range 15-35USD.
I would like to hear what you think of this.
