Help on deciding which board to use

[armuser]

Hi Guys,

I am trying to build solar cell + inverter + SMPS voltage monitor.

The inputs are:

1. Solar PV cell voltage and current.
2. Input voltage from PT (potential transformer)
3. Current through CT (current transformer)
4. SMPS Voltage and Current.
5. Inverter status (on/Battery low/overload)

The outputs are:

1. SMPS switch (ON/OFF)
2. Inverter switch (ON/OFF and RESET)
3. RS232 interface
4. Ethernet
5. GPS
6. GSM/RF (for remote logging capability)
7. LCD
8. USB

The main point of this project is data logging ie. to be able to send an update of the front-end (PV/inverter/SMPS) once every morning, every day remotely. Also should be able to control the system (nos.1 and 2) remotely i.e. through internet.

Based on this, which board should I use? There are so many boards here, I am not sure which one to use.

Also where can I buy the board from?

Thanks a lot for your help.

BeagleBone with rs232 cape would be my choice. But that is because I have been using it for a while and feel comfy with it.
