Seeed Studio XIAO RP2350

Seeed Studio XIAO RP2350 is built around the Raspberry Pi RP2350 chip, a dual-core, dual-architecture MCU that lets you switch between industry-standard Arm Cortex-M33 cores and open-hardware Hazard3 RISC-V cores, all packed into the classic 21 x 17.8mm XIAO form factor. It's compatible with C/C++ and MicroPython, giving you flexibility in both architecture and development environment for a single board.

Dual-Architecture Flexibility

The RP2350 pairs dual Arm Cortex-M33 cores running at 150MHz with FPU alongside a pair of open-hardware Hazard3 RISC-V cores, letting you choose the architecture that best fits your project without changing boards.

Expanded I/O for More Complex Projects

Compared to previous XIAO boards, this one adds 8 new IO pins on the back, bringing the total to 19 multifunction GPIOs covering analog, digital, I2C, UART, SPI, and PWM. That extra I/O headroom makes it a better fit for more complex applications that would otherwise outgrow a standard XIAO board.

Enhanced Security and Power Design

Built-in secure boot and an encrypted bootloader help protect application security. On the power side, the board supports battery power supply with direct battery voltage measurement via internal IO, enhancing the onboard battery management system.

Compact and Production-Friendly

At 21 x 17.8mm, it keeps the classic thumb-sized XIAO form factor. Its SMD design places all components on the front with stamp holes on both sides, suited to efficient mass production as well as bench prototyping.
