Circuit Description
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 X1 provides the IC U6 with the required oscillation frequency to enable the IC U6 to work normally. IC U1 achieves energy-saving control through continuous interactive learning of product operation environment through algorithms. Flash U2、U8 is the external extended memory of the IC U6、U1 for data storage. The IC U3 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, [Name of manufacturer], declares that this [type of equipment] is in compliance with the essential requirements and other relevant provisions of RE Directive 2014/53/EU. A copy of the full DoC is attached.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help
