Description: The Arduino Nano R4 (with headers) is a compact and powerful microcontroller board built around the Renesas RA4M1 32-bit ARM Cortex-M4 processor, delivering improved performance while maintaining the classic Nano form factor for breadboard-friendly prototyping. Operating at 5V logic and fully supported in the Arduino IDE, it is ideal for embedded systems, automation projects, and advanced electronics development where space is limited but higher processing capability is required. The pre-soldered headers allow for quick integration into circuits and existing Nano-based designs. Specifications: Microcontroller: Renesas RA4M1 (Arm Cortex-M4) Clock Speed: 48 MHz Operating Voltage: 5V Flash Memory: 256 KB SRAM: 32 KB Digital I/O Pins: 14 Analog Input Pins: 8 USB: USB-C Form Factor: Nano (pre-soldered headers)
