The Seeed XIAO RP2350 is a compact microcontroller board featuring the Raspberry Pi RP2350 chip - the same found on the Raspberry Pi Pico 2 - which offers dual-core processing and impressive performance for its small size. The board has 11 digital I/O pins, 8 analogue inputs, and support for multiple programming languages, including CircuitPython, Arduino, and MicroPython. Its small size makes it ideal for wearable devices, IoT, and other space-constrained projects. This comes in two options: board + headers and a pre-soldered board option. Please select an option before adding to cart. 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 * Product number: * Board + Loose headers: Seeed 102010550 * Pre-soldered board: 102010637 What's on Board Specifications Processor Raspberry Pi RP2350 Dual Cortex-M33 @ 150MHz, FPU RAM 520kB SRAM Flash 2MB PSRAM LEDs 1 user LED, 1 power LED，1 RGB LED Interface 19 Pins: 3x Analog,19x Digital, 2x I²C, 2x UART, 2x SPI, All PWM Button 1 RESET button, 1 BOOT button Security OTP, Secure Boot, Arm TrustZone Low power 27μA Software compatibility Supports MicroPython / C, C++ Working Temperature -20°C-70°C Dimensions 21 x 17.5 mm Resources * Product Wiki Pinout Package Contents * 1x XIAO RP2350 * Either pre-soldered or board + loose headers (select before adding to cart) https://elecena.pl/product/26738150/seeed-xiao-rp2350 2024-08-09 https://elecena.pl/product/26738150/seeed-xiao-rp2350 2024-09-18 https://elecena.pl/product/26738150/seeed-xiao-rp2350 2024-11-29 https://elecena.pl/product/26738150/seeed-xiao-rp2350 2024-11-30 https://elecena.pl/product/26738150/seeed-xiao-rp2350 2025-09-29 https://elecena.pl/product/26738150/seeed-xiao-rp2350 2025-11-28 https://elecena.pl/product/26738150/seeed-xiao-rp2350 2025-11-29
