TP4056 Type-C Lithium Battery Charging Module (with Protection)
Manage your Li-Ion and LiPo batteries safely and effectively with the industry-standard TP4056 charging module. Upgraded with a modern USB Type-C interface, this board not only charges your single-cell 3.7V batteries but also features built-in protection circuitry to ensure the longevity and safety of your power cells.
Key Features:
- Modern Type-C Input: Say goodbye to outdated cables. Easily power the charging module using your standard smartphone USB-C cable for maximum convenience.
- Integrated Battery Protection (DW01A): Features onboard over-charge, over-discharge, and short-circuit protection. It automatically disconnects the load if the battery voltage drops dangerously low, protecting your cell from permanent damage.
- Adjustable Charging Current: Defaults to a reliable 1A charge rate, which is perfect for most standard batteries. The current can be manually adjusted for smaller capacity batteries by changing the onboard surface-mount resistor (RPROG).
- Clear Status Indicators: Built-in dual LEDs provide instant visual feedback (Red for charging, Blue/Green for fully charged), so you always know your battery's status at a glance.
- All-in-One Power Solution: With dedicated solder pads for battery input (B+/B-) and load output (OUT+/OUT-), this module acts as a complete power management system for your DIY electronics and IoT nodes.
