The USB-A to USB-B 30cm Data Cable for Arduino UNO and MEGA is a short 30cm USB 2.0 cable with a standard Type-A male connector on the PC end and a USB Type-B male connector on the device end, designed for Arduino Uno, Mega 2560, and any other USB Type-B device. The arduino uno cable supports data transfer rates up to 480 Mbps and delivers USB power simultaneously, making it the correct cable for sketch uploading, serial monitor communication, and board power through a single connection.
The USB-B connector on this arduino data cable is the larger square-shaped connector with bevelled top corners — the same connector used on most desktop printers and older USB audio interfaces. This is different from the Mini-B connector used on Arduino Nano and the Micro USB connector used on NodeMCU and Wemos boards. One practical note: the arduino uno with cable combination is ready to use immediately after plugging in — no driver installation is needed for the cable itself, only the CH340 or ATmega16U2 USB-serial chip driver on the Arduino board.
The non-obvious advantage of the 30cm arduino uno cable price point over standard 1-metre cables is signal integrity — shorter cables have lower capacitance and resistance, giving more stable USB communication at high data rates during firmware flashing. Available from StemVolt, this unit is suitable for engineers working on Arduino Uno Mega programming and practical electronics projects.
