Arduino Nano R4 with Headers

The Arduino Nano R4 with Headers combines the powerful Renesas RA4M1 microcontroller with the popular Nano form factor. Factory-installed headers allow the board to be plugged directly into a breadboard or prototype, while the 32-bit Arm Cortex-M4 processor running at 48MHz, USB-C connectivity and modern onboard peripherals make it suitable for education, prototyping and embedded development.

Maintaining the familiar Nano footprint and 5V operating voltage, the Nano R4 is compatible with many existing Nano accessories and shields. It also adds a Qwiic I²C connector, CAN bus, a 12-bit DAC, integrated operational amplifier (OPAMP) and Real-Time Clock (RTC), providing advanced functionality without additional hardware.
