Supplied without a USB cable. Identical to the UNO R3 in terms of functionality (ATmega328P, 16 MHz, standard form factor, and shield compatibility), this version uses surface-mount components (SMD) and a CH340 USB-to-serial chip instead of the ATmega16U2.
The result is a more affordable board, ideal for equipping electronics laboratories or building multiple prototypes, without changing your usual workflow or Arduino code.
