I am looking for a portable device which should fullfill my following requirement:
- Device should be able to connect and communicate with bluetooth devices.
- Device should be able to connect to internet. First preference is wifi connection, but as a fallback mechanism, ethernet will also work.
- I should be able to run Node.js server on it. This server will be very light weight, wont need much RAM and computing resources.
- Less than $30.
Now, after reading few resources i found, Raspberry pi gives me all such features, but only issue with Raspberry pi is that it has many other feature also (camera port, HDMI, etc) which add significant amount to its cost. Since i need device for commercial purpose, so i need to make it cost effective as well.
Can somebody suggest me some available readymade options ?
Note I am looking for device to control some lighting stuff. These device should be used as a gateway and needs to be installed in customer premises. So, thats why these devices should be either a chip/small size board.
