Conversion efficiency: ≤95% (efficiency and input, output voltage,
current, pressure difference)
Installation: 4pcs 3mm column
Connection mode: welding output (please use big current and pure copper wire)
Module size: 130mmx52mmx46mm(LxWxH)
 
Features:
1.Over current protection: there is a certain range of error in the input over 30A,
automatically reducing the output voltage.
2.Short circuit protection: there is (input 40A fuse) double short circuit protection,
use more secure.
 
When using the boost power supply should pay attention to the following points:
1 input power supply voltage must be above 10V.
2 when the power supply is used for the input power supply, the input power and
the output voltage of the input power supply are the first to be unloaded. Then pick
up the load. (must ensure that the switching power supply has been working).
3 when the constant current mode is used to set the voltage, the constant voltage
must be higher than the input voltage.Do not use the way of short ci
rcuit output current,
the circuit structure of the boost module can not be adjusted in short circuit way.
 
Package include:
1x1200W boost constant current module

The ShP Optical Dust Sensor (GP2Y1010AU0F) is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.
An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air.
The sensor has a very low current consumption (20mA max, 11mA typical), and can be powered with up to 7VDC. The output of the sensor is an analog voltage proportional to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3.
For your convenience, ITEAD ship this sensor with a 6-pin, 1.5mm pitch mating connector and cable.

comes example code
direct plug puzzle board, NO soldering needed.
Five momentary push buttons (4 joystick select button, just like the playstation 3 analog stick push button)
two-axis thumb joystick
specification: The push buttons are connected to Arduin digital pins 2-6; the related pin will be low when a certain button is pressed. Joystick
Y-Axis movement will produce a proportional analog voltage on analog pin 0, while, Joystick X-Axis movement will produce a analog signal on analog pin 1.
Add nRF24L01 RF interface
With Nokia 5110 LCD interface, so very easy to game development.
Adding a Bluetooth module interface, convenient Bluetooth wireless serial communication.
Add I2C communication interface, easy connectivity to I2C devices
Meanwhile, JoyStick Shield with a cross PS2 joystick with buttons, there are four round buttons, 2 small buttons. Provides for Arduin joystick and buttons input expansion. Onboard switches can switch between 3.3V and 5V, can use this model for other 3.3V microcontroller platforms, such as STM32.

【 INTRODUCTION 】
With the development of computer technology, parallel port and serial port in PC slowly disappeared, now even the desktop are rare parallel port. But for engineers, parallel ports and serial ports are essential interfaces, especially serial ports. For the computer without serial port, the most convenient solution is to use USB to serial port chip to virtual a serial port out, from the perspective of stability, or FT232 series is the most reliable, you can use it to ease the debugging program without worrying about the blue screen.

Description:
100% brand new and high quality
Material: Electrical components
Color: See pictures
HW-586 battery capacity tester discharge type 1.2-12V 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
