The XIAO RA4M1 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.

Key features
  • Popular Microcontroller Onboard: Powered by Renesas RA4M1, an 32-bit ARM® Cortex®-M4 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 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.
  • Compact Thumb-Sized Design: Measuring 21 x 17.8mm, adopting Seeed Studio's classic XIAO form factor, ideal for space-conscious applications.
  • Production-Friendly: Surface Mount Device (SMD) design with all components on the front and stamp holes on both sides, facilitating efficient mass production.
