3、Circuit Description

Figure1. Circuit Diagram

WIFI module has an independent power management system, and

the system provides a high quality of power supply for the whole

module. The Excellent matching circuit in RF-Front ensures that the

signal has minimal signal loss and radiation. Oscillator Y1 provides the

IC U1 with the required oscillation frequency to enable the IC U1 to

work normally.The IC U1 provides the interfaces for a variety of

peripherals (Timer, PWM, Interrupt, AD, the Debug) from the module

to the baseboard. Each peripheral that connects to the MCU I/O pins

can choose between two different I/O pin locations with the provided

flexibility in various applications.

Hereby, [

],declares that this[

] is in compliance with the essential requirements and other

relevant provisions of RE Directive 2014/53/EU. A copy of the full DoC
