Arduino Zero - 32-bit performance in Arduino's UNO form factor. The Zero is a simple and powerful 32-bit extension to the UNO platform. The Zero board expands the family with increased performance, enables a variety of device project possibilities, and serves as a great teaching tool for learning how to develop 32-bit applications. Zero applications range from smart IoT devices, wearable technology, high-tech automation to crazy robotics. The board is powered by Atmel's SAMD21 MCU, which has a 32-bit ARM Cortex® M0+ core. One of the key features is Atmel's Embedded Debugger (EDBG), which provides a full debug interface without additional hardware, greatly enhancing the user experience for software debugging. The EDBG also supports a virtual COM port that can be used for device and bootloader programming. The board includes everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable or power it with an AC/DC adapter or battery to get started. The Zero is compatible with all shields that operate at 3.3V have the pinout for the Arduino Uno. Technical Features - Microcontroller: ATSAMD21G18, 32-bit ARM Cortex M0+ - operating voltage: 3.3 V - clock frequency: up to 48 MHz - Flash memory: 256 KB bulletpoint# SRAM: 32 KB - 20 digital I/O pins - 6 analog inputs (12-bit ADC) - 1 analog output (10-bit DAC) Note Unlike most Arduino boards, the Zero runs on 3.3 V. The maximum voltage that the I/O pins can tolerate is also 3.3 V. Applying voltages above 3.3 V to any I/O pin can damage the board! https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2021-10-04 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2021-10-25 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2021-11-21 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2022-05-13 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2022-11-07 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2023-09-10 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2025-02-08 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2025-04-07 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2025-09-25 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2025-11-24 https://elecena.pl/product/19556423/abx00003-arduino-zero-samd21-usb-micro 2026-02-20
