About the Li ion charger PCB

Li ion charger is an open source PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 38 × 22 mm, with 25 components from 15 distinct parts.

Other key parts include the TP4056M. By type, the board carries 7 relays, 6 resistors, 3 jumpers, 2 diodes, 2 capacitors and 1 IC.

It belongs with the power & battery designs in this gallery.

From the project

Hardware design, BOM, gerbers and 3D files for Li-ion-charger designed by Soldered Electronics.

Lithium batteries can’t be charged as regular batteries or devices. Instead, you’ll need a li-ion charger such as this one. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery.

The board has a USB Type-C connector for power, a JST-type connector for batteries, the charging circuit, and two status LEDs.

All Soldered Electronics hardware designed in KiCAD, and repositories are organized in the following way:
