This powerful Arm® Cortex®-M4 processor runs at 48 MHz and features a floating-point unit (FPU), making it ideal for complex digital signal processing and edge computing tasks. With 256 kB of Flash memory and 32 kB of SRAM—offering 8x and 16x the capacity of the classic Nano respectively—you will never have to worry about running out of space for your advanced code libraries and variables.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eSeamless Qwiic \u0026amp; Modulino Integration\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThis development board completely streamlines sensor integration by featuring an onboard Qwiic I2C connector. You no longer need to solder complex wiring harnesses or use bulky breadboards to connect external I2C modules; simply plug in any Qwiic-compatible sensor or Arduino Modulino node for instant, reliable communication. This plug-and-play architecture drastically reduces hardware troubleshooting time, allowing makers and engineers to focus entirely on software development and rapid prototyping.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003e5V Logic with Advanced Hardware Peripherals\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThe Nano R4 operates at a standard 5V logic level, ensuring 100% hardware compatibility with your existing shields, sensors, and circuits originally designed for older Nano revisions. Beyond backward compatibility, it introduces advanced peripherals including a 12-bit Digital-to-Analog Converter (DAC) for true analog audio output, a built-in Operational Amplifier (OPAMP), and a CAN bus controller for automotive and industrial networking. It also features a Real-Time Clock (RTC) with a dedicated battery backup pin (VBATT) to keep accurate time even when the main power is disconnected.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003ePro Tip from Our Technicians\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAlways remember that while the main Arduino Nano R4 board operates at 5V logic, the onboard Qwiic I2C connector strictly outputs 3.3V to comply with the Qwiic standard. Our Sham Shui Po DIY specialists strongly advise against connecting 5V sensors directly to the Qwiic port, as this mismatch can damage the components; however, the board's internal logic translator safely handles the communication between the 3.3V Qwiic bus and the 5V microcontroller.\u003c\/span\u003e\u003c\/p\u003e","brand":"Arduino","offers":[{"title":"Default Title","offer_id":48265196798103,"sku":"21CU000172","price":175.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/cover_0a8b10ef-570a-4fb1-990f-64bcd0af8d60.jpg?v=1789373183","url":"https:\/\/scccltd.com\/products\/arduino-nano-r4-with-headers-abx00143","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
