Product Overview
MM3SB3350N3 wireless module is a fully functional, highly integrated, low power consumption dedicated Wi-Fi & Bluetooth module for the Internet of things. It supports IEEE802.11a/b/g/n protocol, also embedded IPV4, TCP, UDP, DNS, HTTP and other complete network protocol, so that the terminal in the Internet of things applications more reliable, convenient and easy to use. MM3SB3350N3 core chip adopts the MT7697D single chip scheme of Media corp. The chip is highly integrated with CPU, PMU, RAM, T/R SW, LNA, PA and other major parts, thus greatly reducing the power consumption of the whole machine. The module adopts the integrated three-dimensional metal antenna design, which can not only reduce the cost of the antenna for customers, but also save the assembly space of the antenna, greatly reduce the area of the board, and make the product more competitive. At present, the module provides a complete serial port interface function to communicate with the device, and can connect the cloud and the device through the serial port and the mobile client.
The module has the following characteristics:
- Support IEEE 802.11a/b/g/n protocol
- Supports 20MHz and 40MHz bandwidth in the 2.4ghz band and 5GHz band
- Support bluetooth BLE 4.2
- The module has a built-in dual-mode metal antenna
- Low power listening mode

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.
MODIFICATION:
Any changes or modifications not expressly approved by the grantee of this device could void the user’s authority to operate the device. Because the working frequency of the device is in 5150-5250 MHZ, so this module is suitable for indoor use of the equipment. This equipment must be installed to provide a separation distance of at least 20cm from all persons.
