1. General Description
WizFi310 module is a Wi-Fi module that fully compliant with IEEE 802.11b/g/n wireless
standards, It combines an ARM-CM3 MCU, WLAN MAC, a 1T1R capable WLAN baseband,
and RF in the module. It have onboard antenna, and external antenna interface, RF output
PIN also exist in the board. WizFi310 internally integrated TCP / IP protocol stack, supporting
numerous protocols such as ARP, IP, ICMP, TCP, UDP, DHCP CLIENT, DHCP SERVER, DNS and
other etc. It supports AP mode, Station mode. It also support rich AT command for all kinds
of application. Users can easily and quickly use it to wifi networking and data transmission.
The baud rate of module serial port is up to 921600bps, which can fully meet the low-rate
applications.
In network part, WizFi310 supports storing network parameters in the module, and
reduce time connect to network. The module has built-in WEB server, supporting wireless
network parameters configuration, supporting wireless firmware upgrade. It also supports
WPS and EasyConfig. In application part, HTTP, MQTT, MDNS and SSL also be supported.
It also provides a bunch of configurable GPIOs which are configured as SPI ,UART, I2C,
I2S, PWM, for different applications and control usage. integrates internal 2M
SRAM ,and 512KB DRAM and 2MB flash for complete WIFI protocol functions.
