I was curious if either of you noticed what WiFi chip or module the unit is using and if it is soldered or possibly socketed to the main board. I was also curious if they shut down the WiFi and the cellular radio when using Ethernet. Someone mentioned that a zigbee radio might be in there too.
Thank you to all.
The wifi chip is really a module made by Unigen. I believe its connected via SDIO and it is this part: http://www.unigen.com/product_detail.php?pid=859
Moral of the story is that the Blink
has no RF shelding and no EMI protection, we're either going to need an external antenna or a whole new wifi module. They were nice enough to connect the WAN modem via a USB-A connector so we can pop that out and use a traditional USB wifi adapter. I run over ethernet for testing and development so I'm not concerned with wifi network connectivity at this point.
The main linux board is a slightly modified Boundary Devices Hydrogen board with a PXA270 on it with other "gue". The lovely folks who built this thing decided they would go with the reference kernel and filesystem from Boundary Devices so it made life a lot easier. I have the cross compiler for the subsystem and have compiled a few applications.
Oh one other piece of information I thought everyone would enjoy. There is a 1/8" audio jack on the main board. I've already played an MP3 out the jack to some speakers. The audio quality is prety darn good. Looks like we have an EVSE + MP3 player!
