## Description

Small but capable, the Arduino Nano R4 with headers packs the Renesas RA4M1 (Arm Cortex-M4) into a tiny 45 x 18 mm board that is ready for breadboards and rapid prototyping.

Use it to make compact projects, connect Qwiic sensors for quick I2C expansion, or embed the board directly into custom PCBs for space-constrained products.
