Welcome to the tag category page for Dual!
RP2040 is Raspberry Pi’s debut 32-bit dual-core microcontroller, designed to bring the foundation’s emphasis on performance, low cost and ease of use to embedded projects. Featuring two ARM Cortex-M0+ cores, significant on-chip RAM and support for C/C++ and MicroPython, it powers low-cost boards such as the Raspberry Pi Pico and smaller variants like XIAO designs. The chip’s USB mass-storage boot, broad IDE compatibility and a port of TensorFlow Lite make it attractive for rapid prototyping, micro machine‑learning, IoT and hobbyist applications. Compared with alternatives like the ESP32, RP2040 trades higher clock speed for architectural simplicity and strong software support; vendor boards and upgraded modules (for example, wireless-enabled RP2040 Connect variants) add sensors, security, and connectivity. Its low unit cost has spurred a wide ecosystem of third‑party modules and development boards, keeping it relevant for education, consumer devices and embedded product development where ease of use and low BOM matter.
