Seeed Studio XIAO RA4M1 Development Board
Seeed Studio XIAO RA4M1 Development Board integrates Renesas' RA4M1 chip (32-bit ARM® Cortex®-M4 MCU up to 48MHz 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, and a 14-bit A/D converter. The XIAO RA4M1 development board is compatible with Arduino IDE for seamless project development and prototyping. This development board provide 4 operating modes with power consumption as low as 45μA in deep sleep and supports lithium battery charge management. Typical applications include smart control, education, robotics, and wearables.
