1. Introduction
MDA1L11-3 Wireless WIFI module is a low-power WIFI module for
the Internet of Things. It supports IEEE802.11b / g / n protocol. It also
embeds IPV4 / IPV6 TCP / IP, HTTP, DNS, FTP and other complete network
protocols, making the terminal more reliable, convenient and easy to
use.
The MDA1L11-3 module contains HolaConW01 single-chip solution.
the chip in software and hardware are used in low-power technology,
the purpose is to lower the power consumption of the entire board, the
product more competitive. At present, the module provides a
complete serial interface functions and equipment to communicate, so
you can through the serial port and mobile client to connect the cloud
and equipment.

1.2 Module System Block Diagram
As shown in Figure 1, the MDA1L11-3 module contains
HolaConW01 single-chip solution. The module uses the internal antenna
design in PCB, both for customers to reduce the cost of the antenna,

but also eliminates the need to consider the antenna assembly space.

Note/FCC warning: 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.
—This equipment should be installed and operated with a minimum distance of
20cm between the radiator and your body.
