The XIAO RP2350 packs the power of the Raspberry Pi RP2350 (switchable architecture of dual Arm Cortex-M33 cores running at 150MHz with FPU, and dual open-hardware Hazard3 RISC‑V cores, enhanced security and encryption) into the classic XIAO form factor. Measuring just 21x17.5mm, it features 19 multifunction GPIOs, an RGB LED, and a Battery Management System with ultra-low power consumption of 27μA, 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.

The ESP32-C3-DEVKIT-RUST-1 from Espressif Systems is a development platform designed for RF, RFID, and wireless applications. Built around the ESP32-C3-MINI IC, it supports Bluetooth (BLE) and IEEE 802.11 b/g/n Wi-Fi at 2.4GHz, providing reliable connectivity for wireless communication projects.
