XIAO RP2350 Onboard RGB LED, Arm Cortex-M33 and Hazard3 RISC-V(Pre-Order)OpenELAB

Description

The XIAO RP2350 packs the power of the Raspberry Pi RP2350 (dual Cortex-M33 cores running at 150MHz with FPU, 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 ultra-low power consumption of 50μA, 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.

Features​

• Powerful MCU Board: Equipped with a Raspberry Pi RP2350 chip featuring symmetric dual Arm Cortex-M33 @ 150MHz with FPU.

• 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 50μA 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 17.8mm, 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.
