Feature

 
  • Powerful MCU Board: Equipped with a Raspberry Pi RP2350 chip featuring dual-core, dual-architecture capability, allowing developers to switch between the dual industry-standard Arm Cortex-M33 cores @ 150MHz with FPU, and a pair of open-hardware Hazard3 RISC‑V cores
  • Enhanced Security Features: Built-in secure boot and encrypted bootloader ensure 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 SRAM, and 19 multifunction GPIOs(Analog, Digital, I²C, UART, SPI, PWM).
  • Expanded 8 New IOs: Compared to previous XIAO MCUs, the addition of 8 IO pins on the back supports more complex applications.
  • Efficient Power Design: Enabling battery power supply. Direct battery voltage measurement via internal IO enhances the battery management system (BMS).
  • Compact Thumb-Sized Design: Measuring 21 x 17.8mm, adopting Seeed Studio's classic XIAO form factor, ideal for space-conscious applications.
  • Production-friendly: Surface Mount Device (SMD) design with all components on the front and stamp holes on both sides, facilitating efficient mass production.

 

 

Production-Ready Design with Fusion PCBA Support

Being the 9th member of the Seeed Studio XIAO family, the XIAO RP2350 remains the classic XIAO design (thumb-size, SMD, stamp holes). All these features make it a perfect fit for either space-limited projects such as wearables, or a production-ready unit for commercial PCBA (Printed Circuit Board Assembly) integration. With our Seeed Studio Fusion services, you can access competitive one-stop PCB fabrication, component sourcing, assembly, and testing, plus free DFA/DFM review to reduce manufacturing risks and accelerate the journey from prototype to production.

Seeed Studio XIAO RP2350

SKU 102010550

The XIAO RP2350 packs the power of the Raspberry Pi RP2350 (switchable architecture of dual Arm Cortex-M33 cores running at 150MHz with FPU, and dual open-hardware Hazard3 RISC‑V cores, enhanced security and encryption) into the classic XIAO form factor. Measuring just 21x17.8mm, it features 19 multifunction GPIOs, an RGB LED, and a Battery Management System with  battery power supply, and direct battery voltage measurement. Thanks to the XIAO ecosystem, the XIAO RP2350 is compatible with a wide range of add-ons, including displays, LED matrix, Grove modules, CAN Bus, Vision AI sensors, and mmWave sensors. With native support for MicroPython, C, and C++, the XIAO RP2350 is perfect for developers of all levels looking to create compact, battery-powered applications for smart control, wearables, DIY keyboards, and more.
