Portable USB Charger (Version 2.0)

Step 4 The Printed Circuit board

The first picture is the circuit that is to be etched onto the PCB, the second picture shows where everything should go.

*Your looking at the side with the copper foil, so watch the polarity when putting in the components

As chrisstoll said, the middle pin of the voltage regulator is supposed to be connected to ground (negative), and the others are input and output (posotive).

very wrong????!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[chrisstoll]

Isn't the inside connector on the voltage regulator ground? And not the outside one as shown in the diagram?

I dont really want to etch a board or drill holes is three any other option

what do with data lead because i try one similar with car mobile charger out put voltage coming 7 volt do we limit voltage arruond 5 volt. and need data lead any resistor required? Vijay Shinde

[princesmay]

i hope u can add some features...and post another interfacing using usb

[kyle910]

Would you mind doing a more detailed walkthrough, and maybe adding more pictures to guide us.
