The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatical..

The output expander module is in reality a serial to parallel converter with 8 output ports per board. Each output ports have LED state indicators. Up to 10 modules can be cascaded to build up to 80 additional output ports with the use of just 3 microcontroller I/O ports. Works with 3.3V and 5V logi..

The input expander module allows addition of 8 or more inputs . Each input is monitored with buffered LED indicators. Up to 10 modules can be cascaded to build up to 80 additional input ports with the use of just 3 microcontroller I/O ports. Works with 3.3V and 5V logic. Specifications :Power In..
