This is DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module, a combo of 2A Charger and voltage checker.
The module converts input of 4.5-40V into a very stable 5V 2A output. The device features a USB port through which you can charge your phone. While charging your device please consider that the output of this device is regulated at 5V 2A.
DC-DC Step-Down Buck Converter Power Supply Module 24V 12V 9V to 5V 5A 25W Replace LM2596S
This DC-DC Step-Down Buck Converter Power Supply Module provides all the active functions for a step-down (buck) switching regulator, capable of driving a load up to 5A with excellent line and load regulation. This module comes with variable but the fixed value of input i.e. 24V, 12V, and 9V as well as fixed output voltage which is 5V 5A.
The module requires a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed frequency oscillator. And hence it replaces the purpose of LM2596S.

DHT22 – Temperature and Humidity Sensor Module
DHT22 capacitive humidity sensing digital temperature and humidity module is one that contains the compound has been calibrated digital signal output of the temperature and humidity sensors. Application of a dedicated digital modules collection technology and the temperature and humidity sensing technology, to ensure that the product has high reliability and excellent long-term stability.
The sensor includes a capacitive sensor wet components and a high-precision temperature measurement devices, and connected with a high-performance 8-bit microcontroller. The product has excellent quality, fast response, strong anti-jamming capability, and high cost.
Standard single-bus interface, system integration quick and easy. Small size, low power consumption, signal transmission distance up to 20 meters, making it the best choice of all kinds of applications and even the most demanding applications.
DHT22 has higher precision and can replace the expensive imported SHT10 temperature and humidity sensor.
It can measure the environment temperature and humidity to meet the high demand.The product has high reliability and good stability.If it's used and combined with special sensor Arduino expansion board,it will be easily implemented the interactive effect which related to the temperature and humidity perception.
Caution: DHT22 digital temperature and humidity sensor is designed for analog sensor interfaces. The analog port will be used as the digital which will not occupy the original digital port of the Arduino.The lines of the sensor which can transform the analog function to digital that can be use on digital port.

Digital DC Mini Voltmeter 0.36 inch – 2 Wire Module – 4.5V to 30V
* Product Images are shown for illustrative purposes only and may differ from actual product.This is tiny and compact digital voltmeter with LED Display. The DC 4.5-30V 2 wire LED Display Digital Voltage Voltmeter Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink!!!!
The red wire is to connect to the positive pole, the black wire is to connect to the negative pole. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection. This voltmeter doesn’t need external drive working power, it can work with measuring voltage, the working voltage’s range is 4.5-30V. To reach the best measurement accuracy, this voltmeter will automatically move the decimal point’s position according to the different measuring voltage. When it measures the voltage below 10V, it will display two places after the decimal point. When it measures the voltage above 10V, it will display one place after the decimal point. This voltmeter can be used to measure the storage battery’s voltage in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other voltage. 30V is the voltmeter’s maximum operating limited voltage, please leave enough margin when working, to avoid voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage. Very bight and decent LED Display is ready to measure the dc voltages in the range of 4.5V to 30V. Connections:-Specifications and Features-:
- Red Wire: source +ve terminal.
- Black Wire: Source -ve terminal.
- Note: The display weight and Dimensions may have ±2% error.

Digital PWM Generator with Display
DIP 3 Color LED Module
This module consists of a 5mm RGB LED and three150 limiting resistorsto prevent burnout. Adjusting the PWM signal on each colour pin will result in different colours.
This isa DIP 3 Color LED Module.Through the PWM adjusting, three primary colours can be mixed to obtain different colours.
Connect the red pin (R) on the KY-016 to pin 11 on the Arduino. Blue (B) to pin 10, green (G) to pin 9 and ground (-) to GND. Notice that you do not need to use limiting resistors since they are already included on the board.
DJI NAZA M-lite Remote LED module
This is the NAZA M-lite Remote LED module by DJI. The M-Lite LED Module now incorporates USB connectivity which makes updating the firmware on the M-Lite module a simple task.
Where a connector is used to Connect to Main Controller LED port and a USB port is used in the PC connection for parameter configuration and firmware upgrade.
