What problem does it solve?

Provides a comprehensive development guide for the Arduino Uno R4 Minima, including pinouts, board specifications, and practical programming guidance to accelerate firmware creation on the RA4M1-based board.

Core Features & Use Cases

  • Pin reference and GPIO mappings for D0–D13, A0–A5, and special functions like CAN, DAC, and RTC.
  • Step-by-step board setup, Arduino CLI integration, and example sketches to demonstrate I2C, SPI, UART, and PWM peripherals.
  • Use Case: a developer wiring sensors to the Uno R4 Minima and implementing a complete firmware loop with serial I/O and peripheral communication.

Quick Start

Connect the Uno R4 Minima to your computer, install the Renesas UNO core in the Arduino CLI, and compile and upload a minimal sketch to verify basic operation.
