SPIDER Automation Adafruit Feather M0 Bluefruit LE Development Board | ATSAMD21 ARM Cortex-M0
Description
SPIDER Automation Adafruit Feather M0 Bluefruit LE Development Board is an all-in-one, Arduino-compatible microcontroller platform combining powerful 32-bit ARM processing with Bluetooth Low Energy (BLE) wireless connectivity, native USB, and onboard battery charging. Built around the popular Adafruit Feather form factor, it is pre-integrated with a high-performance Bluefruit LE module, making it completely ready to rock right out of the box for portable wireless applications.
Bluetooth Low Energy is an ultra-low-power 2.4GHz wireless protocol that stands out as the ideal solution for mobile connectivity because it interfaces seamlessly with iOS devices without requiring special MFi certification, alongside full support across modern Android, Mac OS X, and Windows 8+ environments. At the core of the Feather M0 is the ATSAMD21G18 32-bit ARM Cortex-M0 processor running at 48 MHz with 3.3V logic—providing 256KB of Flash memory and 32KB of RAM. Featuring native USB support for serial programming and debugging, plus an integrated LiPo battery charger with automatic power switching, it delivers an unmatched workstation for untethered IoT prototypes.
