TP4056 Battery Charger C Type Module with Protection The TP4056 1A Li-Ion Battery Charging Board Type C with Current safety is a small module designed for charging single-cell 3.7V lithium-ion batteries, such as 16550s, that do not have their own safety circuit. Using the TP4056 charger IC and the DW01 battery protection IC, this lithium battery charger produces a 1A charging current and will automatically stop charging once completed. Also, if the battery voltage goes below 2.4V, the safety IC will cut off the load to save the cell from functioning at an unacceptably low voltage. The TP4056 charging module also protects against overvoltage and reverse polarity connections, often sacrificing itself to preserve the battery. Just remember to double-check your connections the first time you put it up. Your batteries can be safely and easily charged with TP4056 lithium-ion battery charger. All you need to do is connect it correctly, and it will do the rest. Use the Module Through the Following Steps: To supply power, either plug in a Type C cable or attach a 5V DC source to the IN+ and IN-labeled pads on the module's left side. Fasten the battery that has to be charged to the B+/B- pads on the module's right side. The OUT+/OUT- pads on the right side can also be used to attach a load, or an object that the battery will power. Keep in mind that while the battery is charging, unplug the load. When the charging process is finished, the green LED will turn on, while the red LED will illuminate to signify that the charge is ongoing. Be careful to never charge your battery at a rate exceeding 1C Note: Please remember the following crucial information: The module's 5V input side is the only one to which the ampere meter should be attached. A charging current of around 37% of the battery's capacity is advised. A 400mAh charging current is adequate for a 1000mAh battery. Make use of reasonably thin connecting cables. Verify the security of the connecting point. It is usual for the current to decrease below 1000mA if the input voltage is greater than 5.2V. In order to shield the chip from harm, this protective function immediately lowers the charging current. Reverse polarity should be avoided at all costs. Features It features a modern USB Type-C port that provides convenient and universal power. This module includes integrated protection against over-charge, over-discharge, and short-circuits. It utilizes an intelligent CC/CV algorithm to ensure a fast, safe, and efficient charging cycle. It is equipped with clear dual-LED indicators for at-a-glance monitoring of the charging status. This module is perfectly designed for charging single-cell 3.7V Li-Ion and Li-Po batteries. Its compact and high-precision design allows for seamless integration into any electronics project.

LM2596 DC-DC Buck Module The LM2596 DC-DC Buck Converter Step-Down Power Supply Module is a step-down(buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version. The LM2596 series operates at a switching frequency of 150kHz, thus allowing smaller-sized filter components than what would be required with lower-frequency switching regulators. This buck converter is internally compensated to minimize the number of external components to simplify the power supply design. Since the LM2596 converter is a switch-mode power supply, its efficiency is significantly higher than popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller-sized filter components than what would be needed with lower-frequency switching regulators. Features: Switching Frequency: 150KHz Rectification: Non-synchronous rectification Internally Compensated for minimized external components Efficient operation with higher input voltages compared to three-terminal linear regulators Short circuit protection for current limiting and recovery. Pinout: Pinout Of LM2596 DC-DC Buck Module Applications: Used for USB on the go. Used for Point of load converters for PCs and laptops. Used for Battery Chargers. Used for Quad Copters. Used for Power audio amplifiers.
