Adafruit Feather M0 Wi-Fi ATSAMD21 ATWINC1500 Dev Boards

Adafruit Feather M0 Wi-Fi ATSAMD21 and ATWINC1500 Development Boards are all-in-one Arduino-compatible and high-speed, reliable Wi-Fi development boards with built-in USB and battery charging. Each board features the 48MHz ATSAMD21G18 ARM Cortex M0 processor with 3.3V logic. The processor offers 256K of flash, 32K of RAM, and a built-in USB. The built-in USB provides a USB-to-Serial program and debug capability.

The FCC-certified ATWINC1500 Wi-Fi module allows designers to connect to the Internet. This 802.11bgn-capable Wi-Fi module has built-in low-power management capabilities, Soft-AP, SSL TSL 1.2 support, and highly reliable performance. Through the ATWINC1500, designers can connect to their own Wi-Fi networks or create their own with "Soft AP" mode, so it becomes its own access point. The module provides fast, reliable packet streaming at up to 12MHz. ATWINC1500 also enables scanning/connecting to networks in just a second or two.

To support portable projects, the board includes a connector for Adafruit 3.7V lithium polymer batteries and built-in battery charging.
