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-:

Digital Multi Servo Tester ESC CCPM Consistency Master Speed Control
The Digital Multi Servo Tester ESC RC Consistency CCPM Master Speed Control offers 3 modes to check servos or ESC. The Manual Mode allows you to turn the knob to different speeds and check the reaction time. The Neutral mode makes the servo go back to the neutral point. The Automatic ’’Window Wiper’’ Mode makes the servo swing like a window wiper in the largest angle possible.

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.
Direct V6 J-head Hotend Heatsink for 1.75 mm filament
The Direct V6 J-head Hotend Heatsink for 1.75 mm filament is a filament radiator designed for direct drive 1.75mm extruders andHotend Assemblies and is built to keep filament from melting before it reaches the heat block. This helps to prevent blockages and jams within the cold-endso that it only melts once it is pulled into the heating zone.
The bottom end of the tower has machined thread to connect to the heat break, while the top is surrounded by a shroud to fit a30mm fanand connects to the extruder assembly. The 30mm fan ensures that the filament is maintained at a nice, cool temperature so that it can be extruded with precision accuracy without melting before it needs to. This greatly reduces any chances of filament problems and results in far better quality prints.
Bear in mind that this cooling tower is made for direct drive extruders, so if you are looking for a Bowden-style cooling tower, consider the this V6 Bowden Cooling Towerthat caters universally to both 1.75mm and 3mm extruder assemblies.
This direct V6 J-head Hotend Heatsink for 1.75 mm filament is made to fit 1.75mm diameter direct drive extruder and hotend assemblies like our Charlstruder and Titan Extruder Assembly. It is one of the vital components that keep the filament in ideal condition for quality prints and ensures fewer problems like blockages, jams and leakage.
