Feature:  1. TI's CC3200 solution: based on the ARM Cortex-M4 core, running at up to 80MHz; 2. Ultra-low power consumption: lower power consumption than wifi low-power series, low on-line standby to 3.5mA, deep sleep to 25uA;  3. Ultra-small size: 18.22*26.65*2.8(mm);  4. High-speed UART: baud rate support up to 3M bps (special firmware needs to be upgraded);  5. Simplelink: One-click connection to Wi-Fi network;   6. Dual serial port: Support 2 serial ports;  7. Three links: can support 3 TCP links;  8. Data security: Supports two types of encryption: data PC1 encrypted transparent transmission, SSL Client encrypted submission;  9. More features: support custom web pages, websocket, httpd client;  10. The WIFI module is a transmission module that converts serial port or TTL level to WIFI communication. The WIFI module can realize wireless data transmission, acquisition and control, and can also realize intelligent management of mobile phones and remote servers.    Specification:  Main frequency: 80MHz.  Network parameters: Network protocol: IPv4, TCP, UDP, DHCP, DNS, HTTP, ARP.
