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
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.
-
