TP4056 USB-C charger and protection module

One module per unit ordered.

Great for

Rechargeable 1S lithium projects
Protected 18650 holders and portable builds
Arduino and ESP32 battery-powered projects
Adding USB-C charging to a suitable enclosure

Wiring & getting started

  1. Confirm the cell

    Use one healthy 4.2 V Li-ion or LiPo cell whose charging specification permits the board's nominal 1 A current.

  2. Check the pad order

    With the component side up and USB-C at the left, the right-edge pads are OUT+, B+, B-, OUT- from top to bottom.

  3. Connect the battery

    With USB unplugged, connect battery positive to B+ and negative to B-. Reverse polarity is not protected.

  4. Run a first-power-up test

    Leave the project disconnected, apply 5 V by USB-C, and check for a red charging indicator or blue standby indicator.

  5. Connect the load

    Use OUT+ and OUT-. The output follows the cell voltage and is not a regulated 5 V rail.

Note: This board has no separate load-sharing stage. A running load can delay or prevent normal charge termination, so switch the project off while charging when reliable termination matters. Never charge a damaged lithium cell or leave charging unattended.

Frequently Asked Questions

Answers to the questions buyers ask most.

Which batteries can I use?
Use one rechargeable 1S Li-ion or LiPo cell with a 4.2 V full-charge voltage. Do not use LiFePO4, multi-cell packs or non-rechargeable batteries.
What voltage appears at OUT+ and OUT-?
The protected output follows the cell voltage. It is not regulated to 5 V, so add a suitable regulator if your project needs a fixed supply.
Can I run a load while the cell is charging?
The load and charger share the cell node. A running load can keep current above the charger's termination threshold, so switch the load off when reliable charge termination matters or add a suitable power-path circuit.
Why is there no voltage at the OUT pads?
Disconnect the load, check battery polarity and cell voltage, then briefly apply 5 V by USB-C to release a protection latch. Recheck solder joints and pad continuity if the output remains off.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
