This electronics kit includes an R3 controller board, USB cable, power supply module, 830-point breadboard, jumper wires, Dupont wires, pin headers, precision potentiometer, photoresistors, thermistor, diodes, transistors, ICs, buzzers, push buttons, capacitors, LEDs, RGB LED, and assorted resistors for circuit setup, testing, and prototyping.

Compared with a standard component assortment, this set includes an additional controller board, making it more convenient for breadboard circuit building, module connection, solderless assembly, and repeated testing. The included components are suitable for LED experiments, buzzer applications, input and output practice, and other common prototype tasks.

Package includes 1 R3 controller board with USB cable, 1 power supply module, 1 830-point breadboard, multiple jumper wires and Dupont wires, 2 header strips, 1 precision potentiometer, 2 photoresistors, 1 thermistor, 5 rectifier diodes, 5 NPN transistors, 2 ICs, active and passive buzzers, 10 push buttons, ceramic and electrolytic capacitors, LEDs in multiple colors, 1 RGB LED, and assorted resistor values.

Warning: Do not use voltage higher than 9V with the power supply module.

37 VALUES 480 PCS ELECTRONICS COMPONENT KIT: Includes a UNO R3 compatible board, breadboard, power supply module, jumper wires, LEDs, resistors, capacitors and other commonly used parts for circuit testing.
WITH UNO R3 COMPATIBLE BOARD: More than a standard arduino component kit, this set includes the board and USB cable, so you can connect and test parts without buying them separately.
BREADBOARD KIT WITH POWER SUPPLY: The 830 tie-point solderless breadboard, power supply module and jumper wires make circuit building, part testing and quick changes easier.
COMMON ELECTRONIC PARTS IN ONE BOX: Includes resistors, LEDs, diodes, transistors, buttons, buzzer, potentiometer and other basic components for everyday electronics work.
COMPATIBLE WITH ARDUINO IDE, STM32 AND RASPBERRY PI: Suitable for breadboard kit use, DIY electronics, STEM practice and controller board prototyping. Tutorial lessons are not included.
