I need a printed circuit board (PCB) which should have:
1. Embedded software/firmware, which:
a. Reads register data from a modbus slave device, via RS232/RS485.
b. Sends the data via SMS(Text Message)
c. Sends the data via email
d. Should run 24x7 and do this process ever 4 hours, then go to sleep mode
2. Should have a battery (like one in cell phone)
3. Should work with DC power adapter when AC power supply is available, else battery power should be used.
4. Should have socket for Ethernet cable (RJ 45)
5. Should have socket for Serial cable RS232 and RS485
6. Should have a SIM slot
7. It should be a headless system (no display) but it should have a micro httpd web server, which will serve for device's configuration (similar to those found on routers)
Do get back if you have any further query.

Do you want the PCB or just the design of it? The bid includes the PCB (one unit). If you only need the design (or if you need more units) please contact me.
PXA270, 128MB SDRAM, 128MB CF card, 10/100 ethernet x1, RS232 x 4, USB host x 4, MC35i module, Windows CE v5.0 supported. you can develop the s/w by yourself or we do for you.
I have an existing design that can be taylored to this application. Currently it lacks the GSM module, but for SMS only this is not a huge effort. See PM for more info.
