## Overview

The Seeed Studio XIAO RA4M1 is a compact, pre-soldered development board featuring the Renesas RA4M1 32-bit Cortex-M4 MCU running at 48MHz with FPU. It offers 256KB Flash, 32KB SRAM, and 8KB EEPROM, with 5V tolerant I/O for seamless sensor integration. Equipped with USB-C, CAN Bus, 19 GPIOs, a 14-bit ADC, and a 12-bit DAC, it supports advanced analog and industrial applications. Its ultra-compact 21x17.8mm size and low power modes (as low as 45μA) make it ideal for portable and battery-powered IoT projects, all fully compatible with the Arduino IDE.

## Description

This is the pre-soldered version of XIAO RA4M1， which integrates Renesas' RA4M1 chip (32-bit ARM Cortex-M4 MCU up to 48 MHz with FPU) into the classic XIAO form factor. This development board offers 256KB Flash, 32KB SRAM, 8KB EEPROM, a USB 2.0 connector, reset and boot buttons, 3 LEDs, a 14-bit A/D converter, a 12-bit D/A converter, and a CAN BUS interface. With onboard charging circuitry and low-power modes (as low as 45μA), it’s ideal for battery-powered applications. Sharing the same 32-bit microcontroller as the Arduino Uno R4, it's natively compatible with Arduino IDE, making it the perfect starting point for electronics projects thanks to the extensive XIAO accessories.

Review: Use the DAC! - All XIAO are great little boards. But this one is special if you are interested in analog signals. It has a 12 bit DAC. The R4 is a super Arduino, but overall not a super processor. But at this price, it's a dream.
Review: Seeed Xiao RA4M1 seems to have firmware issues that can result in device brick - I've had one Seeed Xiao RA4M1 brick itself after normal light usage. Completely unusable.

## Features

- Powerful Renesas RA4M1 Core: Features the same 32-bit Cortex-M4 processor used in the Arduino UNO R4 Minima. This board provides a seamless migration path for your projects with high performance (48MHz + FPU) in a fraction of the size. Fully compatible with Arduino IDE
- 5V Tolerant I/O Design: Unlike traditional 3.3V development boards, the XIAO RA4M1 allows direct connection to 5V sensors and peripherals without the need for level shifters, simplifying your circuit design and making it safer for beginners
- Pre-Soldered & Breadboard Ready: Comes with pre-soldered header pins, saving you time on setup. You can plug it directly into a breadboard or connect jumper wires right out of the box—perfect for rapid prototyping and classroom use
- Rich Interfaces & Expansion: Despite its tiny size, it packs a punch with 19 GPIOs (including 8 expansion pads on the back), 14-bit ADC for high-precision sensing, 12-bit DAC, and CAN Bus support for industrial automotive projects
- Ultra-Compact & Power Efficient: Maintaining the classic thumb-sized XIAO form factor (21 x 17.8mm) with USB-C. Supports excellent power management (as low as 45μA in sleep mode) with onboard battery charge management, ideal for wearable and portable IoT devices
