TP4056 1A lithium charging module

1A Constant Current / Constant Voltage Charging: Built around the industry-standard TP4056 linear charger IC, providing a stable, regulated 1A charging current using a Constant Current / Constant Voltage (CC/CV) charging profile.

Mini-USB Power Input Connection: Integrated female Mini-USB input socket alongside direct input solder pads (IN+ and IN-) for flexible power supply connections.

Integrated Battery Protection IC: Equipped with onboard DW01 protection IC and 8205A MOSFET switch guarding against cell overcharging (4.2V cut-off), overdischarging (2.5V cut-off), overcurrent, and output short-circuit conditions.

Real-Time LED Charge Indicators: Onboard surface-mount LEDs provide instant visual feedback (red LED indicates active charging; blue/green LED indicates full charge or standby).

Compact Breakout Form Factor: Ultra-small, lightweight PCB footprint designed for effortless mounting in space-constrained DIY electronics, handheld gadgets, and custom enclosures.

Automatic Charge Termination: Automatically stops charging once the battery reaches full charge (4.2V) and resumes charging if battery voltage drops below 4.05V.

Housing & PCB Style: High-density FR-4 glass epoxy PCB with SMD circuitry and onboard dual status LEDs.

Contact & Terminal Style: Solder pads for BAT+, BAT-, OUT+, OUT-, IN+, IN-, and female Mini-USB input port.

Technical Specifications:

Input Voltage: 4.5V – 5.5V DC (via Mini-USB or solder pads).

Full Charge Cut-Off Voltage: 4.2V -+ 1.5%.

Max Output Charge Current: 1A (Programmable via RPROG resistor).

Overdischarge Cut-off Voltage: 2.5V.

Color: Blue PCB with white component silkscreen markings.

Usage Advice: Double-check cell polarity when connecting to BAT+ and BAT-; reverse polarity will permanently damage the TP4056 chip.

Maintenance: Keep board contacts clean and free of flux residue or moisture. Store in an anti-static pouch when not integrated into a circuit.

Essential Single-Cell Lithium Charger: Position as the core lithium-ion/LiPo charging breakout module for 18650 power packs, custom IoT edge devices, portable Arduino/ESP32 projects, and DIY electronics repairs.

Highlight Dual-Protection Circuitry: Emphasize the onboard battery protection circuitry that ensures safe, worry-free operation without needing external protection boards on your cells.

Recommended Cross-Sell Add-ons: Pair with TP4056 1A lithium charging module Type-C, 5V 1A Mini USB TP4056 Lithium Battery Charger, 2 x 18650 Lithium Battery Shield Power Expansion Board, and ESD antistatic mat 50x40CM PCB Welding Mat.
