The R4 USB B. Connector: What’s Different and What’s the Same?

Arduino has recently released their latest board, the R4 Uno, and it comes with some notable changes. One of the key differences is the new USB Type B connector, which replaces the previous USB Type A connector. In this article, we will discuss the differences between the two connectors and explore what has remained unchanged in the R4 Uno.

Differences: USB B. Connector

The most apparent change in the R4 Uno is the replacement of the USB Type A connector with the USB Type B connector. The USB Type A connector, commonly found in computers and other USB peripherals, is a rectangular-shaped connector. On the other hand, the USB Type B connector, often used in printers and other peripheral devices, is square-shaped with beveled corners. This change in connector type may require users to use a different type of cable or adapter if they previously relied on USB Type A connectors.

What Remains the Same

Despite the changes in the USB connector, Arduino has ensured that several key aspects remain the same in the R4 Uno. The operating voltage of the R4 Uno is still 5 volts, similar to its predecessor, the R3 Uno. This means that users can continue using their shields designed for the R3 without any compatibility issues.
