Kit: Packages that include the main board, guides, and a variety of components (wires, sensors, LEDs); ideal for beginners who want to learn programming and electronics.
Boards: The main boards-microcontrollers (e.g. Arduino Uno, Nano, Mega) that serve as the "brain" of your project, where you upload your code.
Accessories: Additional essential items such as protective cases, power cables, battery holders, and breadboards for your experiments.
Module: Ready-made small circuits with specific functions (e.g. modules for Wi-Fi, Bluetooth, relays, or motion sensors) that can be easily connected to the main board.
Jumper: Special flexible wires with terminals (male or female) for quickly connecting components together without soldering.
Shields: Expansion boards that fit directly on top of the main Arduino board (like a "floor"), instantly adding new features (e.g. Ethernet shield, Motor shield).
Breakout Boards: Tiny boards that "carry" a very small chip (e.g. a sensor) and bring its connections out to more convenient pins, so you can easily connect it with wires.
