Breadboard-Plugin Components Pack is a new kit designed for breadboard experiments. It provides all kinds of components, such as resistors, capacitors, diodes, transistors .etc in just one pack. The module pins are made with gold-plating technology, so solid and durable that can be plugged onto the breadboard directly. Easy, reliable and reusable, this is the Breadboard-Plugin Components Pack. This innovative approach will solve the following issues caused by using DIP type of components: Hard to read the value (Resistor color codes) Severe deformations of the pin after used, non-reusable, not environment-friendly The pin diameter is too thin or too thick, poor match with the breadboard hole Confused the order of transistor “e”, “b”, “c” pins Usage problem: Most of sensors and actuators require 3 interfaces: Signal/VCC/GND, you have to use the jumper wire for the connection, messy and unreliable. Designed by Maker LeoYan, manufactured and sold by DFRobot Features: Easy to Recognize : Resistance value, capacitance values, positive/negative polaron and pin functions are marked clearly. Easy to Learn : The circuit symbol is clearly visible, directly match the circuit diagram Easy to Use : Direct-plug pin Easy to Plug/unplug : The 0.64mm diametral pin matches the breadboard hole perfectly High-Reliability : ENIG technology, the circuit connection is reliable and durable Environment-Friendly : Reusable and Environment-friendly Specification: Operating Voltage: 3.3 ~ 5.5 VDC Output Voltage: 0 ~ 3.0VDC Interface: PH2.0-3P Dimension: 98mm * 23mm (3.86in x 0.905in) Weight: 15g Documents: Wiki Doc Product Includes: Resistor 220R x4 Resistor 1K x4 Resistor 4.7K x4 Resistor 10K x4 Capacitor 22pF x2 Capacitor 100nF x2 Capacitor 47uF x2 LED--R x2 LED--Y x2 LED--B x2 LED--G x2 Diode x4 NPN transistor x2 PNP transistor x2 Breadboard PluginConnector x2
