How to charge the battery: 1. Determine the float voltage and charging current of the rechargeable battery, the input voltage of the module;2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;4. The charge-to-light current is shipped by default at 0.1 times the charge current (constant current value).5. Adjust the constant voltage position device to make the output voltage reach the float voltage; connect the battery and try to charge.(1, 2, 3, 4, 5 steps are the module input power supply, the output is not connected to the battery.)LED constant current drive How to use:1. Determine the operating current and maximum operating voltage at which you need to drive the LEDs;2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;4. Adjust the constant voltage positioner to make the output voltage reach the maximum working voltage of the LED;5. Connect the LED and test the machine. (1, 2, 3, 4 steps are connected to the power supply of the module, and the output is not connected to the LED light.)Description of the communication protocol:1. This module has the function of communicating with the computer, which can facilitate the computer to read the module current and voltage data. 2. Since the output of this module is TTL level, it is necessary to realize communication with the computer, and also convert this level back to the RS232 which can be recognized by the computer. Level, you need to use this cp2102 usb to TTL module to achieve conversion.3. The communication protocol is as follows: Baud rate: 9600 Bps- BB CC ADDR 00 XX XX CRC (current return command)- BB CC ADDR 01 XX XX CRC (voltage return command)- Where BB CC is the frame header (2 bytes)- ADDR is the module address (1 byte)- 00 is the read current command (1 byte)- 01 is the read voltage command (1 byte)- XX XX any value (2 bytes)- CRC CRC check (1 byte)Instrument properties:1.

Product manual：1. Through-beam photoelectric switch (IRSW20B) is a customizable USB button.It is equivalent to a standard HID USB keyboard and mouse. The switch function can be customized to any key,combination, mouse or character string through the supporting software settings. After the definition is completed, no software is required during use.2. Products are widely used in printers, copiers, game consoles, factory inspections, instrument control, equipment, etc. as well as mobile monitoring, proximity switch monitoring and occasions where it is not convenient to use mechanical switches to improve efficiency.3. The switch adopts a through-beam photoelectric trigger mode. The infrared emitting tube in the device emits infrared light. If there is an object in the middle of the groove, the receiving sensor will trigger the corresponding key value if the infrared light is not detected.4. Provides button definition setting software based on Windows system. After setting, you can use it in the following systems: Dos, Win 2000, Win XP, Win vista, Win 7, Win 8, Win10, Linux, Mac, Android.5. Scope of application: office, game, industry, disabled personFunction Description：1. Keyboard function: It can be set to any key value or key combination, for example, to key value A or CTRL+A.2. Mouse function: It can be set to the left, middle, right, forward and backward keys of the mouse, the movement of the X and Y axes, and the up and down scrolling functions of the wheel.3. String printing: You can set up to 38 characters, for example, set "hello!".4. Multimedia function: It can be set as previous song, next song, volume up, volume down and other multimedia control functions.5. Gamepad function: It can be set as up, down, left and right four direction keys and 6 function keys.When you want to change the function of the button, you can use the FootSwitch software to modify the button function:1. Insert the device into the computer USB port2. Run the software FootSwitch3. Click to select the corresponding setting window4. Click or enter the function you want to set5. Click Save to confirm.6. The setting software only supports Windows system. The FootSwitch software is often upgraded. Please follow the latest version.Product specifications:1. Product model: IRSW20B2. Interface type: USB3. Power supply: 5V30mA4. USB cable length: 2 meters (the cable length can be customized)5.
