The Growth Story Behind Arduino

Source | DF Maker Community

Today, Arduino can be said to be popular worldwide, with a large number of electronics enthusiasts and engineers developing their projects based on Arduino.
So, do you know the origins and development history of Arduino?

Origins

In the cold winter of 2005, Massimo Banzi's students complained about the difficulty of finding cheap and useful microcontrollers.

Coincidentally, a Spanish chip engineer visited the school, and Massimo Banzi discussed this

Recommended Stackup and Impedance Design for RK3588 PCB

To reduce the reflection phenomenon during high-speed signal transmission, it is necessary to maintain impedance matching at the signal source, receiving end, and transmission line. The specific impedance of a single-ended signal line depends on its line width and its relative position to the reference plane. The line width/spacing of differential pairs with specific impedance requirements depends on the chosen PCB stackup structure. Since the minimum line width and minimum spacing depend on the type of PCB and cost requirements,
