The Adafruit ATWINC1500 WiFi Breakout with uFL Connector adds 802.11b/g/n WiFi connectivity to your Arduino or other microcontroller project over SPI. This version features a uFL antenna connector instead of an onboard antenna, allowing you to use an external antenna for improved range or placement flexibility.
Built around the Microchip ATWINC1500 module with firmware 19.4.4, this FCC-certified breakout delivers reliable wireless networking with TLS 1.2 support. Level shifting and a 3.3V regulator make it compatible with both 3V and 5V logic systems.
Key Features
- 802.11b/g/n WiFi – Connect to standard wireless networks with fast scanning and connection
- uFL Antenna Connector – Use an external 2.4 GHz antenna for improved range and flexible placement
- 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
- FCC Certified – Ready for use in finished products
Also Available
- ATWINC1500 WiFi Breakout with Onboard Antenna – No external antenna required
Ideal For
- Projects requiring extended WiFi range with an external antenna
- Enclosures where the antenna needs to be mounted externally
- IoT devices requiring secure TLS connections
- Wireless data logging and sensor networks

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.
- 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.
