Adafruit WICED Wi-Fi Feather Development Board

Adafruit WICED Wi-Fi Feather Development Board is based on the Infineon Technologies WICED (Wireless Internet Connectivity for Embedded Devices) Wi-Fi platform and the 120MHz STM32F205 ARM Cortex M3 processor. The processor and Wi-Fi chipset support the Arduino IDE. Using this board, designers can write code in the Arduino IDE using the same standard libraries (Wire, SPI, etc.), compile locally, and flash the device directly from the IDE over USB. The WICED Wi-Fi Feather Development Board supports TLS 1.2 to access sites and web services safely and securely.
