Product details
Seeed Studio XIAO RP2350 Development Board
The Seeed Studio XIAO RP2350 is a powerful and compact development board designed for a wide range of embedded applications.
It integrates the Raspberry Pi RP2350 processor, featuring dual Arm Cortex-M33 cores running at 150 MHz and dual open-hardware RISC-V cores, offering enhanced performance, security, and encryption capabilities.
With support for MicroPython, C, and C++, developers can easily create versatile, battery-powered projects such as smart controls, wearables, and DIY keyboards.
Measuring only 21x17.8 mm, the board includes 19 multifunction GPIOs, an RGB LED, and a Battery Management System with ultra-low power consumption of just 27μA.
Thanks to the XIAO ecosystem, the XIAO RP2350 seamlessly supports various add-ons, including displays, LED matrices, Grove modules, CAN Bus, Vision AI sensors, and mmWave sensors, making it a perfect choice for efficient and compact embedded system development.
Compatible Accessories
• XIAO Boards
• IoT Wireless
• Electronic Components
Features:
•
Powerful MCU Board: The Raspberry Pi RP2350 processor has dual-core, dual-architecture capabilities, allowing developers to choose between two industry-standard Arm Cortex-M33 cores @ 150MHz with FPU and two open-hardware Hazard3 RISC-V cores.
•
Enhanced Security Features: The built-in secure boot and encrypted bootloader provide application security.
•
Software Support: Compatible with C/C++ and MicroPython, allowing for easy project development and prototyping.
•
Rich Onboard Resources: Includes an RGB LED, 2MB Flash, 520kB SRAM, and 19 multifunction GPIOs (Analog, Digital, I²C, UART, SPI, PWM).
•
Expanded 8 New IOs: Compared to prior XIAO MCUs, the addition of 8 IO pins on the back allows for more complicated applications.
•
Efficient Power Design: In sleep mode, the device consumes only 27μA, making it suitable for battery power supply. Direct battery voltage measurement via internal I/O improves the battery management system (BMS).
•
Compact, thumb-sized design: It is 21 x 17.8mm and uses Seeed Studio's iconic XIAO form factor, making it excellent for space-conscious applications.
•
Production-friendly: Surface Mount Device (SMD) design features all components on the front and stamp holes on both sides, allowing for efficient mass manufacture.
