【General Parameters】Model: KY-040, Working Voltage: 5V, One round number of pulse: 20. | 【No Limited Rotation Counts】The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited. | 【Encoder Key】With the key on the rotary encoder, you can reset to the initial state, that is, counting from 0. | 【Application】Best choice for stepper and servo motor control. You could also use it to control devices like digital potentiometer. | 【Package Included】5 x KY-040 360 Degree Rotary Encoder Module + 5 x Encoder Push Button

【The Most Complete Electronic Starter Kit】The chosen components are the most complete mix to support a huge variety of projects. Including breadboard jumper wires kit, PCB soldering kit, LEDs & resisitor kit and other useful components, such as capacitor, diode, photocoupler, button, buzzer, potentiometer etc. Very easy to get started! | 【Breadboard Power Supply】The core module of the starter kit, which power through USB power cable or power by 9V 1A DC adapter. Lamp/digital display tube/diode/buzzer/PCB soldering experiments are both based on this power module. | 【Breadboard Jumper Wires Kit】Our kit comes with breaboard, power supply, pin header and also each type of jumper wires - ribbon cables / U-shape wires / solderless flexible wires, with which you can do all kinds of circuit experiments. | 【PCB Soldering Kit】Our kit also add single-sided PCB board, double-sided PCB board, solder wire, you can also learn how to solder running LEDs and blink it. | 【Relaiable Technical Support】Detailed tutorials and datasets can be provided for free, please contact us at any time by email to get the eletronic documents, with which you can learn to code and program faster and easier with all the components.

【13-Channels Dual-Pass Power Supply】The PCB power distribution board can distribute 1-channel dual-pass power supply into 13-channels dual-pass power supplies, which is convenient for the power supply of multiple electrical appliances. | 【Three Connection Methods】The design of the power distributor can make it have three ways of use. First: directly divide the positive and negative poles of 1 channel power supply into 13 channels. Second: You can connect several PCB power distribution board to expand more power interfaces. Third: You can short-circuit any interface at both ends of the power distribution board to achieve the effect of a multi-point interface of single-pass circuit. | 【Built-in Double-Layer Wiring】The double-layer thick wiring is used inside the PCB board, which has a better power flow effect, and there will be no poor power contact or power failure. | 【High Quality Copper Material】The wiring terminals are made of high-quality copper pin terminals to ensure the stability and reliability of the circuit. The working voltage is 24V and the output current is 10A. It is suitable for DC and AC power distribution. | 【Satisfaction Guarantee】High quality and customer satisfaction are our top priorities. If this product doesn’t live up your expectations, contact us and we will solve it to make sure that you are happy with your purchase.
