Description
Product Introduction:
The TYPE-C lithium battery charging dimming module is compact in size and does not require the plug to be divided between front and back. It is suitable for production, DIY low-power desk lamps, wooden products, and small night lights. The external welding can be modified with an extension cable to charge DC interface, adapting to various scenarios and flexible applications. Dimming smooth eye protection without screen flicker; Adopting capacitive touch sensing, anti-interference, high sensitivity, long service life, the board comes with battery overcharging and discharging protection. Lithium batteries do not require a protective board, making them more suitable for 18650 lithium batteries and saving costs
Product Parameters:
Product size:35mm*17mm(approximately)
Charging voltage:TYPE-C input DC 5V, does not support fast charging head, fast charging head voltage is high, exceeding 5V is easy to burn out, supports back soldering wire input DC 5V charging
Charging indicator:When there is no battery, plug in 5V and the green light will light up, and the charging red light will turn to green when fully charged
Charging current:450-500mA(approximately)
Battery input:Board identification: BAT+ Connect the positive and negative terminals of the battery; 3. 7V polymer or single 18650 lithium battery(It is recommended that the maximum battery capacity should not exceed 3000ma. The larger the capacity, the longer the light endurance, and the longer the charging time)
Definition of touch:Identification on the board:TOUCH is the welding point of the touch lead (the touch line should be short or thin, and no more than 15 centimeters is preferred)
Output definition:On board identification:LED+light source positive pole, LED-light source negative pole
Output voltage:equal voltage output; The output is a lithium battery voltage, which cannot be used as a substitute for the boost board without boosting
Output power:board It comes with two 3-ohm current limiting resistors, with a limit of about 600 milliamperes and an output of about 3 watts. If larger power is needed, the two empty solder pads on the back of the resistor position can be short circuited to achieve unrestricted output. Limited by the power of the components, the maximum load should not exceed 2A, which means the total power should not exceed 8W
Control mode:capacitive human sensing touch control
Inductive penetration:Paired with touch copper sheet, it can penetrate non-metallic materials 0-3mm; If a metal shell desk lamp is used, the shell must be perforated for installation, and an isolation touch head is optional
