PWM to Voltage Module
(PWM to Voltage Converter Module 0% -100% to 0-10V for PLC MCU Digital to Analog Signal PWM Adjustabl Converter Power Module) 1. Description: The PWM transfer voltage module LC-LM358-PWM2V converts the PWM digital signals into 0 to 10V analog signals. It can be used as signal interface switching for PLC or other industrial control boards. The output voltage is regulated by adjusting the duty ratio of the PWM. The modules are small in size and easy to use in different places. 2. Features: 1>. MCU embedded technology 2>. Easy to operate, fine tuned by potentiometer 3>. Select the PWM signal input level range through short-circuit 4>. The module is smaller, easy to carry and use 3. Parameter: 1>. Work Voltage:DC 12V-30V; (> 100MA) 2>. PWM Receiver Frequency:1KHZ-3KHZ 3>. PWM signal input level range: The peak of 4.5V to 10V level. The short cap install in ‘5V'. This level is used for normal controller or 5V MCU The peak of 12V to 24V level, so inserted in 24V. The short cap install in ‘24V'. This level is used for normal PLC controller 4>. Conversion range:0% -100% PWM to 0-10V 5>. Allowable error:5% 4. Hardware Interface: VCC DC 12V-30V GND Ground PWM Positive of PWM input signal GND Negative of input signal VOUT Output Voltage 0-10V GND Output Voltage Ground 5. Operation instructions: After power on, without input signal, the output is 0V, so only input can output. The first time when the power is on, it is best to do a calibration debugging:Input a 50% duty ratio signal to PWM/GND and adjust the relative amplitude short cap. The frequency is 1KHZ-3KHZ, Measured VOUT and GND with a multimeter and it will display 5V. Adjust potentiometer to make sure display 5.00V on multimeter. This will calibrate your pulse signal to this module. When the frequency changes, the correspondences may be offset and need to be re calibrated. The output voltage can be adjusted by adjusting the duty ratio. The accuracy can be controlled by adjusting the potentiometer.

GY-21 HTU21D Temperature Humidity Sensor Breakout Board Module
The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor.
This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems.
All you need is two lines for I2C communication and you'll have relative humidity readings
and very accurate temperature readings as a bonus!
There are only four pins that need to be hooked up in order to start using this sensor in a project.
One for VCC, one for GND, and two data lines for I2C communication.
This breakout board has built in 4.7k pull up resistors for I2C communications.
If you're hooking up multiple I2C devices on the same bus, you may want to disable these resistors.
It's summer and you're sweating and your hair's all frizzy and all you really want to
know is why the weatherman said this morning that today's relative humidity would max
out at a perfectly reasonable 52% when it feels more like 77% .
Enter the HTU21D-F Temperature Humidity Sensor - the best way to prove the weatherman wrong!
This I2C digital humidity sensor is an accurate and intelligent alternative to the much simpler
Humidity and Temperature Sensor - SHT15 Breakout It has a typical accuracy of ±2% with an
operating range that's optimized from 5% to 95% RH. Operation outside this range
is still possible - just the accuracy might drop a bit. The temperature output has
an accuracy of ±1°C from -30~90°C. If you're looking to measure temperature more accurately,
we recommend the MCP9808 High Accuracy I2C Temperature Sensor Breakout Board.
 
Such a lovely chip - so we spun up a breakout board that includes the
Filtered version (the white bit of plastic which is a PTFE filter to keep the sensor clean),
a 3.3V regulator and I2C level shifting circuitry. This lets you use it safely with any kind
of microcontroller with 3.3V-5V power or logic. Each order comes with one fully assembled
and tested PCB breakout and a small piece of header.
You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.

PD decoy module PD23.0 to DC DC trigger extension cable QC4 charger 9V 12V 15V 20V
 
PD decoy module uses 2721 hardware PD chip, can't be upgraded, can't change voltage, can't solve compatibility problem
      PDC004 uses a hardware PD identification chip.The identification logic of this identification chip is: tricking to trigger a fixed voltage.However, if the voltage that needs to be deceived is not available, the voltage will be applied to the next file.
      For example: 15v product PDC004, your PD power supply is only 12V,Or no 15v next file is 12v,then the scammer will apply to the next 12v. 
PD spoofing is a strict communication format, there will be no spoofing of higher voltages, and no voltage will be boosted or stepped down. It does not have the ability to change the power, voltage, and current of the power supply.
 
Note:
1. The hardware chip will randomly apply for voltage, for example, you need a 15V model.
    It may produce other voltages
2. Hardware chip, can not be upgraded, can not choose voltage
3. Does not support charging head information reading
4. Does not support other gears except for fixing a few voltages, such as PPS gear
5. You forced a 12V tablet computer with 15V, causing the computer to overheat and cause a fire.
6. Does not support PPS gear arbitrary voltage selection
7. Does not guarantee compatibility with most charging heads

 About Drv8825
 
Introduction:
 
The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.
 
The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
 
The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).
 
Features:
 
Simple step and direction control interface
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
Can interface directly with 3.3 V and 5 V systems
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
Short-to-ground and shorted-load protection
4-layer, 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad below the driver IC on the bottom of the PCB
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
45 V maximum supply voltage
Built-in regulator (no external logic voltage supply needed)

 About A4988
 
Introduction:
 
This product is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product. This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A.
 
The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program.The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
 
 
Feature：
 
Simple step and direction control interface;
 
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step;
 
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated;    
 
Voltage to achieve higher step rates;
 
3.3 and 5 V compatible logic supply
 
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay);
 
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection;
 
Short-to-ground and shorted-load protection.
