Description

Introduction

RAK473 is a WiFi 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. RAK473 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, RAK473 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. RAK473 integrates internal 2M SRAM ,and 512KB DRAM and 2MB flash for complete WIFI protocol functions.
