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.
Steps 2 and 3, consistent with the output voltage calibration method.

ZB2L3 battery capacity tester discharge type 1.2-12    V external load capacity of the battery and other tests 18650
Tools, single-function, by controlling the load off and get real-time integrated discharge current capacity results
Maximum support 15V 3A discharged through the discharge voltage and current, itself does not discharge
Maximum capacity statistics support 9999Ah (9999000mAh)
Automatically identify and develop appropriate battery termination voltage can also be manually adjusted  
 
Specifications:
Power supply voltage: DC4.5-6V (micro USB connector)
Operating Current: less than 70mA
Discharge voltage: 1.00V-15.00V 0.01V resolution
Termination voltage range: 0.5-11.0V
Supported by current: 3.000A 0.001A resolution
Maximum voltage measurement error: 1% 0.02V
Maximum current measurement error: 1.5% - 0.008A
Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on.
Board size: 50mmX37mm
Finished Size: 50mmX37mmX17mm (length X width X height maximum position size, contains copper foot height)  
 
Instructions:
1. The first test should be fully charged battery.
2. Connect the battery to be tested positive to positive input, a negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the output of the positive and negative output, to work through the tester micro USB power supply (not available desktop or laptop USB powered), then the battery voltage.
3. Direct start test need only one press of the "OK" button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing " " or "-" buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the "OK "start testing.
4. After the start of the test the tester will control the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A) and battery voltage (V) between the wheel was. When the battery voltage reaches the set cut-off voltage, load control switches off the tester display data stays in capacity (Ah) and above and the corresponding indicator flashes quickly together, now displays the actual capacity of the battery is discharging capacity, about the press "OK" to terminate flashing allows stable data display, press again "OK" button to return to the power-on state can just replace the battery test the next section ......  
 
Error codes and their meanings:
Err1: battery voltage is above 15V
Err2: battery voltage is lower than the termination voltage
Err3: Battery can not afford to load or discharge current line too much resistance
Err4: overcurrent (current exceeds 3.1A)  
 
Note:    Use the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety!
This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminals (absolute 0V) will show 0

1. Description:
This product is a stereo Bluetooth amplifier module. The Bluetooth version is 4.2.
 
2. Features:
1>. The version is 4.2. It can be compatible with all mobile phones and Bluetooth adapters on the market.
      2>. The distance is 15 meters in open space.
      3>. It supports automatically connecting devices that have been paired and playing music automatically.
      4>. F class power amplifier 5W 5W, high power output, over 8002 sound quality.
      5>. It supports USB sound card, no drive, plug and play.
      6>. Good sound quality, suitable for upgrading and refitting the idle sound box and DIY production.
 
3. Instructions:
      1>. Support USB sound card, free drive, plug and play (normal lithium battery power supply situation).
      2>. This product has dual 5W power amplifier circuit. It can not be used in addition to the power amplifier. The output of two amplifiers can not be connected in parallel or connected to the negative electrode, otherwise the power amplifier chip will be damaged.
      3>. There are two 2-8 European and 3-10W speakers respectively, and 3 European 5W and 4 European 10W horn are used. The output is stereo.
      4>. Maximum working current is 5V 2A, using 5V 2A or more voltage power supply, sound quality will be better.
      5>.It is suggested that a 3.7-5V lithium battery (the lithium battery needs a protective plate! It can charge a lithium battery with a USB rechargeable battery, and the USB port can not be used as a power supply port.) or a 5V adapter be used for power supply. It can not use voltage and current unstable power supply, such as dry battery, portable charger, multi-function transformer and so on.
      6>. When the Bluetooth board is installed, the antenna should not be close to the metal parts so as not to affect the transmission distance.
 
4. Operation:
      Start the cell phone Bluetooth, scan the device, find the "DW-CT14 " to click connection.
 
5. Note:
The charging interface of this product is a current limiting charging mode without charge management. For your safety, be sure to use a regular lithium-ion battery with a protective plate, which can cause loss due to improper use.
