◆ Product Description

The CM-WIFI module is a compact and powerful integrated 802.11 b/g/n WIFI low-power solution developed by Shenzhen Gumei Technology Co., Ltd. The module comes with a RS485 port and a standard RS232 communication port. Through the CM-WIFI module, traditional serial devices such as PLC and instrument can be easily connected to the WIFI wireless network for transparent transmission, thus realizing the IoT network control and management.

The CM-WIFI-L is available with a lithium battery.

The module uses the industry's lowest power embedded architecture and is optimized for low-flow, low-frequency data transmission in smart homes, smart grids, handheld devices, personal healthcare, and industrial control.

Features:

● Supports STA/AP/STA+AP coexistence working mode.

● Support Smart Link intelligent networking function (providing APP).

● Completely replace the wired cable and realize the direct connection and configuration between the PLC and the computer (host computer).

● Built-in WIFI module, 300MW transmit power, easy to cover 100m scene, wireless programming, debugging and monitoring in any corner.

● Cross-regional connection, no need to set complex parameters in the off-site, both plug and play. Easily control the remote PLC at home or in the company, avoiding troubles on business trips.
