The Metro M0 Express board provides an advanced experience over the original Metro 328, featuring a ATSAMD21G18 ARM Cortex M0+ processor clocked at 48 MHz. With 256K of FLASH and 32K of RAM, it offers significantly more storage and performance.The built-in USB-to-Serial capability eliminates the need for additional chips, allowing seamless program and debugging. Its versatility extends to CircuitPython and Arduino IDE compatibility.Power can be supplied via a 7-9V DC jack or a micro USB connector that intelligently switches between sources. With 25 GPIO pins, multiple hardware interfaces, and a 3.3V logic level, it's capable of handling various tasks, from acting like a serial device to performing as a keyboard or MIDI device.Highlighted features include four indicators and a NeoPixel LED for easy debugging. The onboard 2 MB SPI Flash storage can act like a tiny hard drive, functioning as a storage for scripts or data logging.The easy reprogramming process is simplified with a pre-loaded UF2 bootloader. No extra tools are needed—just drag and drop your firmware. The board comes assembled with headers and includes rubber bumpers for stability, ensuring a plug-and-play setup. https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-10-30 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-11-01 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-11-14 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-11-21 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-11-29 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-12-04 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-12-15 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-12-21 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-12-26 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2025-12-31 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-11 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-14 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-17 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-22 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-25 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-27 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-01-30 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-02-02 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-02-04 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-02-12 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-02-18 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-04 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-09 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-11 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-14 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-16 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-18 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-25 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-28 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-03-31 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-04-05 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-04-12 https://elecena.pl/product/29465246/adafruit-metro-m0-express-designed-for-circuitpython 2026-04-16
