5A DC-DC adjustable step-down module with a voltmeter
One: Product Description
This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module,capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation.The module with a voltage meter to display the input voltage and output voltage, and the voltage can be corrected through the button to improve the accuracy of the voltmeter.
Features:
1. LED power indicator.
2. Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value).
3. Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate!
Voltmeter calibration method:
(1) Output voltage calibration steps
Step 1, adjust the right button so that "OUT" LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and "OUT" LED flashes in synchronization so that you enter the output voltage calibration mode.
Step 2, press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.
Step 3, press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.
(2) Input voltage calibration steps
Step 1, adjust the right button so that "IN" LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, release, voltmeter and "IN" LED flashes in synchronization so that you enter the input voltage calibration mode.

Description:
 
 
Sensiron Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses.
 
Unlike earlier SHT sensors, this sensor has a true I2C interface, and (bonus!) even with two address options. It also is 3V or 5V compliant, so you can power and communicate with it using just about any microcontroller or microcomputer.
 
Such a lovely chip - so we spun up a breakout board with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. 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.
 
 
 
Power Pins:
 
 
Vin - this is the power pin. The chip can use 2.5-5VDC for power. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like for Arduino, use 5V. For a 3.3V controller like a Raspbery Pi, connect to 3.3V
GND - common ground for power and logic
 
 
I2C Logic pins:
 
SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin has a 10K pullup resistor to Vin
SDA - I2C data pin, connect to your microcontrollers I2C data line. This pin has a 10K pullup resistor to Vin
 
 
Other Pins:
 
ADR - This is the I2C address selection pin. This pin has a 10K pull down resistor to make the default I2C address 0x44. You can tie this pin to Vin to make the address 0x45
RST - Hardware reset pint. Has a 10K pullup on it to make the chip active by default. Connect to ground to do a hardware reset!
ALR - Alert/Interrupt output. You can set up the sensor to alert you when an event has occured. Check the datasheet for how you can set up the alerts
 
 
 
Package Included:
 
 
1 X Sensiron SHT31-D Temperature Humidity Sensor

Solve the pain point that some products can not be used during the charging process. When powered by USB alone: The red light flashes, indicating that the power supply is normal. When powered by a separate battery: The yellow light is always on, indicating that the battery power supply is normal; the yellow light flashes, indicating that the battery is low. When the USB and battery are connected at the same time: The red light flashes to indicate that the battery is charging; the red light always indicates that the battery is fully charged. (Note that if the USB input is suddenly disconnected during the charging and discharging process, there will be a few seconds of interruption due
to the charge and discharge mode switching at this time, after which Bluetooth will automatically restart, automatically connect and maintain the previous playback state) Incoming voice call function: After the Bluetooth is connected, turn on the call audio mode in the Bluetooth settings. If the phone calls, you can answer or hang up the phone through the PLAY/STOP button. You can choose to send from the microphone of the original headset (provided that the headset has a call function, which is a 4-segment type) or from the onboard microphone (default), see the function description for details. When the computer sound card is used: Tin the pads in the two boxes corresponding to the Sound Card on the back of the module, and then connect it to the USB interface of the computer through the USB cable, which can be used as a sound card.
