It should be noted that the design and function of the specific TP4056 charging module board may vary by manufacturer and model, so it is recommended to carefully consult the relevant product instructions and specifications before use to ensure proper operation and safe use.


The TP4056 charging module has no discharge function and can only be charged. The charging voltage stops when it reaches 4.2V. The charging current can be adjusted through the resistance of pin 2 of the chip.


TP4056 charging source module board is a lithium ion battery charging control module, using constant current - constant voltage charging mechanism, can charge lithium batteries and provide over charge protection, over discharge protection, over current protection and short circuit protection functions.

The module consists of a TP4056 charger IC and a DW01A lithium-ion battery protection IC. Among them, the TP4056 charger IC is responsible for controlling the charging process, charging at constant current or constant voltage according to the voltage and current of the battery, and providing functions such as soft start, overcharge protection and overdischarge protection. The DW01A lithium-ion battery protection IC is responsible for monitoring the battery voltage and current, and cutting off the output power in time in the case of overdischarge, overcurrent and short circuit to protect the battery from damage.

When using the TP4056 charging source module board, it is necessary to connect the positive and negative terminals of the lithium battery to the B and B- pins on the module board, respectively, and apply 5V power through the USB data cable or pad IN and IN-. During the charging process, the red LED on the module board will indicate the charging status, and the green LED will light up when fully charged. At the same time, the module board also supports an ampere-adjustable charging current and can be adjusted by connecting a 1kΩ resistor to the IN-pad.

In summary, the TP4056 charging source module board is a fully functional, easy-to-use lithium-ion battery charging control module suitable for battery charging and management in a variety of small electronic devices.
