SMT Low Power WIFI Module
USR-C322 is a wifi module released by USR IOT,which has the features of minisize,low power and industry-grade. The hardware of USR-C322 wifi module integrates MAC,baseband chip, RF transceiver unit and power amplifier.
USR-C322 wifi module adopts CC3200 chip of TI,which has industrial ARM Cortex-M4 core and ultra-low power operation mechanism.And it supports WiFi protocol and TCP/IP protocol.User can achieve the function of UART devices connecting to Internet with simple configuration.
USR-C322 Evaluation Board : USR-C322-EVK
C322 supports five power modes,which has Min.3.5mA standby power and has Min.25uA deep sleep power.Its power control can be the highest level.
The above is function structure chart of C322 firmware V2.0.Blue part is for original function, orange for new features of V2.0. New features of firmware V2.0 includes double serial,three links,PC1 Encrypt,SSL encryption submission,http and Websocket communication mode.
C322 has double serials and three network links.
UART 0 supports two network links and one link supports TCP Server;UART 1 supports one network link.
1.Communication with two servers:two UARTs connect with two different servers and receive different commands for the servers;
2.Data backup and remote debugging:serial data sent to the two servers by using two network links of UART 0;
3.TCP Server and TCP Client can work at the same time;
Firmware V2.0 has two encryption communication methods:
PC1 Encrypt:wifi module receives data,encrypts the data with PC1 Encrypt and sends the data to server; SSL Client:use SSL Client to submit data to server;
C322 built-in webpage supports user-defined functions.
C322 supports function of Ethernet to serial, which adopts HTML5 Websocket technology. Combined with custom webapge function, User can design built-in webpage to realize webpage control and data acquisition according to project requirement.
After go into sleep mode,C322 will go through three stages:
① average current of 3.5ma in sleep mode;② after data sent to wifi module,wifi module wakes up quickly and begins to send data;③ if no data sent to wifi module within 10s,wifi module will enter sleep mode again.
Data sending test:
network termination sends 34000 bytes at a time and serial receives 34000 bytes;
network termination data wakes up wifi module and transmits to serial without data loss.
