The Itead Gboard is different. It has all of the peripherals on-board, leaving no general purpose I/O as you would think of it, making it most useful for centralized processing, like in home security and control, process control, or the like. The list of peripheral devices and interfaces is impressive:
The LCD interface supports touch screen LCD modules with the same pinout as the Itead ITDB02 module. The SIM900 GSM module is a popular cellular module, and the nRF24L01+ is the most common 2.4GHz transceiver module.
