=== USB and Battery Charger board ===

Here is a short descrition of the USB and Battery Charger board for my Wave Bubble 2010.\\

Due to hardly available parts on Digikey the battery charging circuit was modified and uses now an LTC1730-4.2
LiPo charger IC.
The LTC1730-4.2 handles charging of a single LiPo cell and includes overcurrent and overtemperature protection
for the battery. The board connects through a mini-USB connector either to a PC for data transfer or to a
wall adapter for charging.\\
Charging current depends on the external power supply but overcurrent protection is set to 2A.
A green LED will indicate charging status.\\
\\
USB data transfer is handled by a simple USB-RS232 converter, the FT232L.\\
\\
Board size is 77mmx52mmx7mm without battery.\\
Maximum battery size: 65mmx35mm\\
