Features Microchip Atmel ATMEGA328P Microcontroller 16-MHZ Crystal Clock. ICSP interface uses USBTiny for programming the Microcontroller UART Communication Module (RS232) SPI Communication ATmega328P I2C Communication Module SPI SD Card for data logging power outages I2C Real Time Clock with date and time Time Stamp provides year, month, day, hours, minutes, seconds Automatic switching to battery on main power loss. Captures Power Failures with time and date stamp written to SD Card. Captures Power Restored with time and date stamp written to SD Card. Captures system resets with time and date stamp written to SD Card. Three time log registers triggered from battery switch-over as well as input driven events. Featuring clock output and two independent interrupt signals.
