Madefree Wifly Breakout
This is a breakout board of the Wifly GSX module.
The WiFly GSX module is a stand alone, embedded wireless 802.11 networking module.
Because of its small form factor and extremely low power consumption, the RN-131G is perfect for mobile wireless applications such as asset monitoring, GPS tracking and battery sensors.
The WiFly GSX 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.
Dimension: 44×34 mm
