Solar USB Charger PCB

Solar USB Charger PCB

Cancelled

Job Description

I have a small PCB that converts a solar panel input to USB standard 5V that needs to be optimized in a couple of ways, including size, recognition of fast charging standards (apple divider dcp 2.0 / 2.7v on data lines, 1.2V on data lines for samsung devices) and some kind of capacitive buffer (to avoid stop charging during very short shadow periods). The goal is to have a ready to be printed pcb layout and part list in industry standard (gerber?) format that can be printed online.
