Popular Microcontroller Onboard: Powered by Renesas RA4M1, an 32-bit R7FA4M1AB3CFM MCU operating at up to 48 MHz with FPU, 256 KB of Flash memory, and 32 KB of . Highlighted Onboard Resources: Equipped with a 14-bit ADC, 12-bit , CAN BUS, USB 2.0, and an onboard RGB LED. Expanded 8 IOs: Adds 8 IO pins on the back compared to previous XIAO boards (19 GPIOs in total), enabling more complex applications. Powerful Security Features: Built-in hardware encryption, secure boot, key storage, and other functions to application security. Software Compatibility: Fully compatible with for IDE for seamless project development and prototyping. Efficient Power Design: Offers 4 operating modes with power consumption as low as 45μA in deep sleep, and supports lithium battery charge management. Production-Friendly: Mount Device (SMD) design with all components on the front and stamp holes on both sides, facilitating efficient mass production. Product Introduction: XIAO RA4M1 integrates the RA4M1 chip into the classic XIAO form factor. The development board provides 256KB flash memory, 32KB , 8KB EEPROM, USB 2.0 connector, reset and buttons, 3 LEDs, 14-bit A/D converter, 12-bit D/A converter, and CAN BUS interface. With onboard charging circuitry and low power mode (down to 45μA), it is ideal for battery-powered applications. It shares the same 32-bit microcontroller as the for R4, is natively compatible with the for IDE, and is the perfect starting point for electronic projects thanks to the rich XIAO accessories.
