The Adafruit ATWINC1500 WiFi Breakout adds 802.11b/g/n WiFi connectivity to your Arduino or other microcontroller project over SPI. Built around the Microchip ATWINC1500 module, this FCC-certified breakout delivers reliable wireless networking with TLS 1.2 support for secure connections.

With built-in level shifting and a 3.3V regulator capable of handling 300 mA spikes, this board works with both 3V and 5V logic systems. Three controllable status LEDs provide visual feedback for connection state and data transmission. The onboard PCB antenna means no external antenna is required.
