TTL, RS232, RS485 three kinds of interfaces. Choice for users.
In the work on, EZ50 There are two ways of working, first for the conventional model,
which module is powered On, is in receive mode; you also can be sending data. The second is
sleep mode, that is, through the power module in a dormant state, it must be user-controlled
mode wake-up pin block, the module can send and receive data.
In the application of EZ50 module, the module uses a wide voltage range, but also
divided into two kinds of voltage, the first for the 5V power supply module, also known as
conventional module, the voltage of DC 4.5V -5.5V. users in the use of power to DC power
supply, the current must be greater than 200mA, but to choose a good power supply ripple.
