En curso Pagado a la entrega

Required is a power supply & battery charging circuit design. Fabrication of the module is not required.

Subject to the specifications below, required for delivery is:

- circuit board BOM (incl manufacturer part numbers)

- design files (preferably EasyEDA, but Kicad, Eagle or Altium OK)

- detailed description of circuit operation

Specifications:

- usb-c in

- 3 voltage rails (plus gnd) out: 3.3v, 5v, 12v.

- combined rail supply 1.5A+

- SMD parts

- <= US$3.50 components at volume of 1,000 pcs

- <= 20mm*40mm.

- 0.5-1A charging with under/over protection & low voltage cutoff.

- When USB-C wall supply is plugged in, operates off wall supply only, when wall supply disconnected switches to battery seamlessly.

- low heat

- if possible... remaining battery level reporting.
