The Atmel® ATWINC3400-XSTK evaluation kit is a hardware platform to evaluate the Atmel® WINC3400-MR210CA module and CRTX-M0+ referance.

Atmel® SmartConnect-WINC3400 is an IEEE 802.11 b/g/n/BLE4.0 IOT network controller SoC. It is the ideal add-On to existing MCU solutions bringing WiFi and BLE Network capabilities through UART or SPI-to-WiFi interface. The WINC3400 connects to any Atmel AVR or SMART MCU with minimal resource requirements. The WINC3400 most advanced mode is a single stream 1x1 802.11n mode providing up to 72 Mbps PHY throughput. WINC3400 features fully integrated Power Amplifier, LNA, Switch and Power Management. ATWINC3400 also features an on-chip microcontroller and integrated flash memory for system software with built in coexistence mechanism for concurrent Wi-Fi & BLE functionality. The only external clock source needed for the WINC3400 is a high-speed crystal or oscillator with a wide variety of reference clock frequencies supported (between 12 – 32 MHz). The WINC3400 is available in a QFN package.
