XIAO RP2350

Thumb-sized (21×17.8 mm) development board powered by the Raspberry Pi RP2350 dual-core MCU (Cortex‑M33 @150 MHz), 520 KB SRAM, 2 MB flash, 19 GPIOs, RGB LED, secure boot & TrustZone, and battery management support—all with ultra-low sleep current (~50 µA). Programmable via MicroPython, C/C++, and CircuitPython—ideal for TinyML, wearables, low‑power IoT, and embedded projects in Sri Lanka.
