## Description

The Feather M0 Basic Proto is the no-frills member of the Feather M0 family, built around the ATSAMD21G18 ARM Cortex M0 processor with a built-in prototyping area for soldering on extra components. With 256KB of flash and 32KB of RAM, it provides significantly more processing power than ATmega-based Feathers. The ATSAMD21 — the same chip used in the Arduino Zero — includes native USB support, a 10-bit DAC output, and PWM on all pins. The 32.768 kHz crystal provides a precise clock source for RTC applications. Key Features ATSAMD21G18 @ 48 MHz – ARM Cortex M0, 3.3V logic 256KB Flash + 32KB RAM – No EEPROM Native USB – Built-in USB bootloader and serial port debugging Built-in Prototyping Area – Solderable space for quick component additions 32.768 kHz Crystal – For clock generation and RTC 20 GPIO Pins – PWM on all pins 6× 12-bit Analogue Inputs – Higher resolution than ATmega-based Feathers 1× 10-bit DAC Output – True analogue output Hardware Serial, I2C & SPI – Full peripheral support Built-in LiPo Charger – 100 mA charging with status indicator LED Battery Monitoring – Battery voltage routed to an analogue pin via divider 3.3V Regulator – 500 mA peak current output Pin #13 Red LED – General-purpose blinking Specifications Dimensions – 51 × 23 × 8 mm (without headers) Weight – 4.6 g Mounting – 4 mounting holes Also Available Feather M0 Adalogger – With MicroSD card holder Feather M0 Bluefruit LE – With Bluetooth Low Energy Feather M0 Express – Designed for CircuitPython Feather M0 WiFi – With ATWINC1500 Wi-Fi Feather M0 RFM95 LoRa Radio (900 MHz) Feather M0 RFM69HCW Packet Radio (868/915 MHz) Ideal For Quick prototyping with onboard solderable area Projects requiring true analogue output (DAC) Expanding with FeatherWing add-on boards Stepping up from ATmega-based boards Package Contents 1× Assembled and tested Feather M0 Basic Proto 1× Header set Note: LiPo battery and USB cable are sold separately.
