Fully compatible with Arduino IDE, it supports 5V tolerant I/O, CAN Bus, USB-C connectivity, and features onboard battery charging with ultra-low power sleep modes, making it ideal for rapid prototyping, industrial IoT, and wearable applications. ## 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. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DRNXF88Z | | Best Sellers Rank | #1,129 in Single Board Computers (Computers & Accessories) | | Brand | seeed studio | | Built-In Media | / | | CPU Speed | 48 MHz | | Compatible Devices | Arduino boards, Raspberry Pi models, XIAO accessories | | Connectivity Technology | USB 2.0, CAN BUS | | Customer Reviews | 4.6 out of 5 stars 12 Reviews | | Included Components | / | | Manufacturer | seeed studio | | Memory Storage Capacity | 256 KB | | Model Name | 102010638-FA | | Operating System | Linux | | Processor Brand | Renesas | | Processor Count | 1 | | Processor Speed | 48 MHz | | RAM Memory Technology | SRAM | | Total Usb Ports | 1 | | Warranty Description | 2 year | ## Product Details - **Brand:** seeed studio - **CPU Speed:** 48 MHz - **Connectivity Technology:** USB 2.0, CAN BUS - **Memory Storage Capacity:** 256 KB - **Model Name:** 102010638-FA ## Images ![Seeed Studio XIAO RA4M1 Dev Board, Compatible with Arduino IDE, Based on Renesas RA4M1 (Chip Used in UNO R4 Minima), 5V Tolerant, CAN Bus, USB-C, Ultra-Compact (Pre-Soldered) - Image 1](https://m.media-amazon.com/images/I/51HoDgH7JZL.jpg) ![Seeed Studio XIAO RA4M1 Dev Board, Compatible with Arduino IDE, Based on Renesas RA4M1 (Chip Used in UNO R4 Minima), 5V Tolerant, CAN Bus, USB-C, Ultra-Compact (Pre-Soldered) - Image 2](https://m.media-amazon.com/images/I/61eYkgD7v8L.jpg) ![Seeed Studio XIAO RA4M1 Dev Board, Compatible with Arduino IDE, Based on Renesas RA4M1 (Chip Used in UNO R4 Minima), 5V Tolerant, CAN Bus, USB-C, Ultra-Compact (Pre-Soldered) - Image 3](https://m.media-amazon.com/images/I/61eYpXWmGTL.jpg) ![Seeed Studio XIAO RA4M1 Dev Board, Compatible with Arduino IDE, Based on Renesas RA4M1 (Chip Used in UNO R4 Minima), 5V Tolerant, CAN Bus, USB-C, Ultra-Compact (Pre-Soldered) - Image 4](https://m.media-amazon.com/images/I/512qtGDozEL.jpg) ![Seeed Studio XIAO RA4M1 Dev Board, Compatible with Arduino IDE, Based on Renesas RA4M1 (Chip Used in UNO R4 Minima), 5V Tolerant, CAN Bus, USB-C, Ultra-Compact (Pre-Soldered) - Image 5](https://m.media-amazon.com/images/I/51vz6ndXzpL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on February 16, 2026* ### ⭐⭐⭐⭐⭐ Review *by B***N on March 8, 2025* ### ⭐⭐⭐ Review *by R***S on September 25, 2025* ## Frequently Bought Together - Seeed Studio XIAO RA4M1 (Pre-Soldered) - Seeed Studio XIAO ESP32 S3 Sense - 2.4GHz Wi-Fi, BLE 5.0, OV2640 Camera Sensor, Digital Microphone, 8MB PSRAM, 8MB Flash, Battery Charge Supported, Rich Interface, IoT, Embedded ML … - Seeed Studio XIAO SAMD21 - Smallest Arduino Compatible Microcontroller with Rich Interfaces, 1pc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/696285472-seeed-studio-xiao-ra4m1-dev-board-compatible-with-arduino-ide](https://www.desertcart.co.uk/products/696285472-seeed-studio-xiao-ra4m1-dev-board-compatible-with-arduino-ide) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
