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.
Key Features
- 802.11b/g/n WiFi – Connect to standard wireless networks with fast scanning and connection
- SPI Interface – Up to 12 MHz clock speed for reliable, high-throughput communication
- TLS 1.2 Support – Secure client connections with firmware 19.4.4
- WEP, WPA, and WPA2 Encryption – Compatible with all common network security protocols
- Soft AP Mode – Create ad-hoc networks for direct device-to-device communication
- Level Shifting – All input pins shifted for 3V or 5V logic compatibility
- 3.3V Voltage Regulator – Handles 300 mA spikes, power from 3–5.5 VDC
- 3× Status LEDs – Controllable via SPI or the Arduino library (SSID connected, data transmit)
- Onboard PCB Antenna – No external antenna required

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.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- 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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- MQTT
- A lightweight messaging protocol often used for IoT devices to publish and receive data through a server called a broker. It matters for home automation and sensor networks because it is simple, efficient, and widely supported.
- 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.
- 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.
