Powerful MCU Board: Equipped with a for- RP2350 chip featuring symmetric dual Arm -M33 @ 150MHz with FPU. Enhanced Security Built-in secure boot and encrypted bootloader application security. Software Support: Compatible with C/C++ and MicroPython, ensuring easy project development and prototyping. Rich Onboard Resources: Integrates an RGB LED, 2MB Flash, 520kB , and 19 multifunction GPIOs(Analog, Digital, I²C, UART, SPI, PWM). Expanded 8 IOs: Compared to previous XIAO MCUs, the addition of 8 IO pins on the back supports more complex applications. Efficient Power Design: Ultra-low power consumption of just 27μA in sleep mode, enabling battery power supply. Direct battery voltage measurement via internal IO enhances the battery management system (). Production-friendly: Mount Device (SMD) design with all components on the front and stamp holes on both sides, facilitating efficient mass production.
