## Description

The Feather M0 WiFi with uFL pairs the ATSAMD21G18 ARM Cortex M0+ processor with an ATWINC1500 Wi-Fi module, featuring a uFL connector instead of an on-board antenna. This allows you to connect an external 2.4 GHz antenna for improved range or custom antenna placement in enclosures. The ATWINC1500 handles all Wi-Fi networking on a dedicated chip, freeing the main processor for your application code. It offers low power consumption (~12 mA active, ~2 mA sleep), SSL/TLS 1.2 support, Soft-AP mode, and WEP/WPA/WPA2 encryption with fast scanning and reliable streaming. Key Features ATSAMD21G18 Processor – ARM Cortex M0+ running at 48 MHz, 3.3V logic 256 KB Flash + 32 KB RAM – No EEPROM ATWINC1500 Wi-Fi Module – FCC-certified 802.11b/g/n with uFL antenna connector SSL/TLS 1.2 – Secure connections handled by the Wi-Fi module Soft-AP Mode – Create your own wireless access point Low Power Wi-Fi – ~12 mA active (WINC) + ~10 mA (ATSAMD21); Wi-Fi module sleeps at ~2 mA 600 mA Regulator – AP2112K-3.3 regulator supports Wi-Fi transmit peaks up to 300 mA Native USB – Built-in USB-to-Serial for programming and debugging 20 GPIO Pins – Hardware Serial, I2C, and SPI; 8× PWM, 10× analogue inputs, 1× analogue output 200 mA LiPo Charger – JST connector with charging status LED and battery voltage monitoring SWD Debug – SWDIO/SWCLK pads on the bottom for CMSIS-DAP debugging Slightly Larger – 53.65 mm × 23 mm × 8 mm (2.6 mm longer than standard Feathers), weighing 6.1 g Important: This version does not include an on-board antenna. A 2.4 GHz antenna with uFL connector is required and sold separately. Note: CircuitPython is not supported on this board — the ATWINC1500 Wi-Fi stack does not fit in the ATSAMD21's memory. Use Arduino IDE for development. Also Available Feather M0 WiFi – Same board with on-board antenna Feather M0 Express – CircuitPython with 2 MB flash Feather M0 Basic Proto – Prototyping area Feather M0 Adalogger – MicroSD data logging Feather M0 Bluefruit LE – Bluetooth Low Energy Feather M0 RFM95 LoRa 900 MHz – Long-range LoRa radio Feather M0 RFM69HCW 868/915 MHz – Packet radio Ideal For Enclosure-mounted projects needing external antenna placement Applications requiring extended Wi-Fi range Battery-powered IoT devices with low power requirements Custom antenna configurations Package Contents 1× Feather M0 WiFi with uFL (ATSAMD21 + ATWINC1500) 1× Header pin set Note: External 2.4 GHz uFL antenna, LiPo battery, and USB cable sold separately.
