Wi-Fi 802.11 b/g to Serial Port Converter
Part number: ATC-2000WF
In Stock : Available

The ATC-2000WF is a stand alone, wireless 802.11 networking module.  Because of its small form factor and extremely low power consumption, the ATC-2000WF is perfect for mobile wireless applications such as asset monitoring, GPS tracking and battery sensors. The ATC-2000 module incorporates a 2.4GHz radio, processor, TCP/IP stack, real-time clock, crypto accelerator, power management and analog sensor interfaces.  This complete solution is preloaded with software to simplify integration and minimizes development of your application.  In the simplest configuration the hardware only requires four connections (PWR, TX, RX, GND) to create a wireless data connection. Additionally, the sensor interface provides temperature, audio, motion, acceleration and other analog data without requiring additional hardware. The ATC-2000WF is programmed and controlled with a simple ASCII command language.   Once the ATC-2000WF is setup it can scan to find an access point, associate, authenticate and connect over any Wi-Fi network(The ATC-2000WF only have UART function. Others functions only appear in embedded module)Block Diagram.
