As I was looking for a power solution for my Boostuino project the Microchip's MCP1642 boost regulator. Finally it was not suitable for that project, but I realized this could be a good candidate for the USB Booster:

available locally for reasonable price

low size/value external components needed due to the high switching frequency

So based on these factors I designed a circuit for it.

The circuit is available in its newly created gihub repo:
