Raspberry Pi Pico W H is an enhanced version of the original Raspberry Pi Pico, a small ( only 6 gr.) , affordable, and versatile microcontroller board. Introduced by the Raspberry Pi Foundation, the Pico W H adds wireless networking capabilities to its feature set, distinguishing it from its predecessor. It incorporates a 2.4 GHz Wi-Fi module, specifically the Infineon CYW43439 chip, enabling Wi-Fi 4 (802.11n) connectivity. This integration allows the Raspberry Pi Pico W to connect to wireless networks, making it ideal for IoT (Internet of Things) projects and applications that require remote data transfer, control, or monitoring. With its low cost, compact design, and flexible programming options, the Pico W is designed to be accessible for hobbyists, educators, and professionals alike, aiming to provide a platform for learning, experimentation, and developing innovative embedded systems.
