pico-usb-wifi firmware converts the Raspberry Pi Pico W into a driverless USB WiFi adapter
Summary
The article reports on pico-usb-wifi, an open-source firmware that turns the Raspberry Pi Pico W into a driverless USB WiFi adapter using a Layer-2 bridge. It exposes a USB CDC-NCM interface, supports IPv4/IPv6 without NAT, and includes a management console and WPA2/WPA3 security; throughput is around 4.75 Mbps, with limitations due to USB 1.1. The project is hosted on GitLab and framed as a low-cost emergency connectivity solution for IoT and embedded devices.
