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

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. Powerful Security Features: Built-in hardware encryption, secure boot, key storage, and other functions to ensure application security.. 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
