M30 wifi module: TTL 3.3V
The startkit include four parts: the test board, the M30 module, the power supply and the antenna.
HLK-M30 is a new low-cost embedded UART-ETH-WIFI module (serial port - Wireless network) developed by Shenzhen Hi-Link Electronic Technology co., Ltd
This product is an embedded module based on the universal serial interface network standard, built-in TCP / IP protocol stack, enabling the user serial port, wireless network (wifi) interface between the conversions.
Through the HLK-M30module, the traditional serial devices do not need to change any configuration; data can be transmitted through the Internet network. Provide a quick solution for the user’s serial devices to transfer data via Ethernet.
This module is with lower power 3.3V 100mA, start time only need 1 second. Smart size, only 14.1*16.5*2.25mm, A key configuration ,easier secondary development.
