I am thinking to start a business in home security/control. I am looking for a cheap solution. The best hardware I would think of would have lots of I/O (maybe 40 lines...), low power consumption, 2 or 3 UART, USB plug. On the other hand, probably no need for PC features like LCD control, HDD, Ethernet links etc... I do not really care about the type of CPU. Mots of the tasks would be routine checking and communication. No display management etc... It means that porcessing power would be low. Communications, programming etc... would be done through serial link. Idea of cost would be in the range of 100 to 150 USD/EURO
Does any one know about Hardwares brands that would fit?
Thank you in advance
Patrick
