Pico Server

Micro-web server functionality on the $6 Raspberry Pi Pico W, enabling compact, Wi-Fi-connected IoT control and data logging.

The Pico Server is a high-efficiency web server implementation running on the Raspberry Pi Pico W (RP2040 chip). Leveraging its integrated 2.4GHz 802.11n Wi-Fi, the $6 microcontroller hosts basic, local web applications using MicroPython or the C/C++ SDK. Its memory-efficient design (264KB SRAM) is critical, restricting it to serving static pages, simple APIs, and real-time sensor data (e.g., controlling an LED or reading temperature) over a local network for robust, low-power Internet of Things (IoT) projects.
