Arduino WiFi 101 Shield

The Arduino Wifi 101 Shield is a powerful IoT shield with crypto-authentication which allows you to wirelessly connect your Arduino or Genuino with ease. This shield is perfect for your IoT projects!
Arduino WiFi 101 Shield is a powerful IoT shield with crypto-authentication, developed with ATMEL, that connects your Arduino or Genuino board to the internet wirelessly. Connecting it to a WiFi network is simple, no further configuration in addition to the SSID and the password are required. The WiFi 101 Shield comes with an easy-to-use library that allows to connect your Arduino or Genuino board to the internet with few instructions. As always, every element of the platform – hardware, software and documentation – are freely available and open-source. This means that you can learn exactly how it's made and use its design as the starting point for your own projects.
  • Operating voltage both 3.3V and 5V (supplied from the host board)
  • Connection via: IEEE 802.11 b/g/n for up to 72 Mbps networks
  • Encryption types: WEP and WPA2 Personal
  • Support TLS 1.1 (SHA256)
  • Connection with Arduino or Genuino on SPI port
  • Onboard CryptoAuthentication by ATMEL
You can find here your board warranty informations.

The WiFi 101 Shield needs certificates to ensure SSL connection. To upload new certificates and update the firmware, please refer to the Utilities section in the WiFi101 Library reference.
