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 SRAM. Highlighted Onboard Resources: Equipped with a 14-bit ADC, 12-bit DAC, CAN BUS, USB 2.0, and an onboard RGB LED. Expanded 8 New IOs: Adds 8 new 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 ensure application security. Software Compatibility: Fully compatible with for Arduino 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: Surface 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 SRAM, 8KB EEPROM, USB 2.0 connector, reset and start 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 Arduino Uno R4, is natively compatible with the for Arduino IDE, and is the perfect starting point for electronic projects thanks to the rich XIAO accessories.
