The TP4056 1A Li-Ion Lithium Battery Charging Module Mini B USB is a 3.7V lithium battery charger module with an onboard Mini USB interface. It is designed for easy battery charging via a computer USB port or an external power source. The module features internal PMOSFET architecture for efficient operation and includes various safety features such as thermal feedback and charge cycle termination.
It is important to note that this breakout board does not have overcurrent protection, so it is recommended to connect an ammeter in series with the 5V input end. The charging current should be around 0.37 times the battery capacity for optimal performance. Additionally, ensure good contact between the board and the battery for reliable operation.
The TP4056 module features a charging indicator with RED LED for charging and BLUE LED for full charge status. The charge current is set at 1A by default but can be adjusted by modifying the onboard resistor. The module uses the TP4056 charging chip for simple peripheral circuits and high charging accuracy.
Package Includes: 1 x TP4056 1A Li-Ion Lithium Battery Charging Module Micro B USB
