Add WiFi connectivity to your Arduino-compatible board with the Adafruit WINC1500 WiFi Shield, featuring the FCC-certified ATWINC1500 module from Atmel. This 802.11b/g/n shield supports WEP, WPA, and WPA2 encryption with TLS 1.2 for secure connections, and communicates over SPI at speeds up to 12 MHz.
The shield includes onboard level shifting for 3V or 5V logic boards, a 3.3V regulator rated for 300 mA spikes, three user-controllable LEDs, and a microSD card socket for data storage or hosting. This version features a built-in PCB antenna. Works best with SAMD21-based boards like the Metro M0 Express or Arduino Zero; also compatible with Arduino Mega.
Key Features
- 802.11b/g/n WiFi – WEP, WPA, and WPA2 encryption with TLS 1.2 support
- SPI Communication – Up to 12 MHz clock speed for fast, reliable data streaming
- Soft AP Mode – Create ad-hoc networks for direct device connections
- Built-in PCB Antenna – No external antenna required
- 3V & 5V Compatible – Onboard level shifting and 3.3V regulator (handles 300 mA spikes)
- MicroSD Card Socket – Store or host data (requires SAMD21-based board for simultaneous WiFi + SD use)

Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- PCB antenna
- A PCB antenna is an antenna pattern built directly into the circuit board rather than a separate metal antenna. It matters because placement, nearby metal and enclosure design can affect wireless range.
- SAMD21
- The SAMD21 is a Microchip microcontroller used in many Arduino-compatible boards. It matters here because USB host library support can depend on the exact microcontroller on your mainboard.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
