| - | === 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\\ | ||
