From the project

6 1S lipo cells charger with BT2.0 connectors - 1A charge current (each) - USB-C PD powered

12V via USB-C PD is requested. If the supply will comply 12V Vbus goes trough an 8A buck conveter to deliver 5V to each of 6 individual 4.35V 1A charger IC.

A green LED indicates 12V rail from PD present.

Green and red leds near each BT2.0 connector indicates charging status.

The BOM is made with JLCPCB component list in mind. Current production quote is 39€ for 2 pcs.
