Olimex OLIMEXINO-328 Development BoardOlimex OLIMEXINO-328 Development Board is compatible with Arduino open-source electronics prototyping platform on which its designed is based. Olimex OLIMEXINO-328 Development Board employs ultra low power voltage regulators with a power consumption of only a few microamps, which enables use in handheld and battery-powered applications. To this end, the OLIMEXINO-328 has a Li-Ion rechargable battery power supply option with a built-in, on-board charger, so that when the user attaches a battery, it is automatically charged and kept in this state until another power source (USB or external adapter) is removed, at which time the battery will automatically power the board.
The OLIMEXINO-328 board also has a UEXT connector which allows many existing modules like RF, ZIGBEE, GSM, and GPS to be connected. It can operate on a power supply of either 3.3V or 5V which is selectable by switch. The power supply also accepts external power from 9 to 30V DC thus making it possible to use virtually any power supply adapter on the market, and also enabling applications which operate on 24V DC industrial power supplies. The board allows Real Time Clock (RTC), has 4 mounting holes to make board attachment easier, and all components work reliably in temperature ranges from -25 to +85ºC.
