Meaning: yes, you can serve a website ***over serial*** with a $1.30 chip.

Probably cheaper to get a $5 MilkV Duo with a $5 ethernet + usb board. Could probably fit a nice sqlite3 db on it too then.

Web hosting bills getting too expensive? Maybe you ought to consider serving your site from a one-dollar 8-bit microcontroller.

Okay, you won’t exactly be serving up a high-performance, graphic-rich website using this

The bargain-basement chip that serves as the central component of this project is the

Serving a web page from such a limited chip is a task, to say the least, and Maurycyz had to do a lot of legwork to get the thing working.
