Seeed Studio XIAO RP2350

The Seeed Studio XIAO RP2350 is a highly capable MCU board that fits the classic, thumb-sized XIAO form factor (21×17.8mm). It is built around the Raspberry Pi RP2350 chip, which features symmetric dual Arm Cortex-M33 cores running at 150MHz with a Floating-Point Unit (FPU). It significantly expands I/O capabilities compared to previous XIAO boards, offering 19 multifunction GPIOs. With an efficient power design, it boasts an ultra-low power consumption of just 50uA in sleep mode and includes a Battery Management System (BMS) for LiPo batteries, making it perfect for secure, battery-powered wearables and IoT applications.
