  1. On the schematic there are two keys — K1 and K2. Function of K2 is obvious (switching module from transparent to command mode and back). But what K1 ????
    It is connected to the EN pin, but there is no expalnation of function in the table. Expecting it is ENABLE pin, is the pin active low or active high? Is pulled down or up? What happens if K1 is pressed?
