 Main System has basic circuit blocks, e.g. Processor (i.MX37), Mobile DDR RAM, Flash Memory, Power Block, Audio
DAC and a block for the FM-Tuner. The display is connected to a 2.6 inch QVGA TFT LCD.
 Serial interface among ICs is delivered with various protocols throughout the overall system.
 The power can be turned on and off with the power switch on the right hand side of the product. The source of power
BAT
is the built-in battery or an adaptor with 5V input. The power from the adaptor can be used for charging the battery and
Li-Polymer
generating the system power (3.0V, 1.2V, 1.8V).
