XIAO RP2350 Onboard RGB LED, Arm Cortex-M33 and Hazard3 RISC-V(Pre-Order)
Product Link
Introduction
The XIAO RP2350 is an innovative development board that combines the power of the Arm Cortex-M33 and the Hazard3 RISC-V cores, offering a versatile platform for developers interested in both traditional and RISC-V architectures. This board is particularly appealing for projects that require low power consumption, advanced processing capabilities, and a compact form factor. Additionally, it features an onboard RGB LED, which can be used for various indications and effects in your projects.
Features
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: Ultra-low power consumption of just 27μA in sleep mode, enabling battery power supply. Direct battery voltage measurement via internal IO enhances the battery management system (BMS).
Compact Thumb-Sized Design: Measuring 21 x 17.5mm, 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.
