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… (Seeed SKU 102010551; also 102010638)
