Sprinkler Controller 2.3 (OpenSprinkler)

Alternative layout of  OpenSprinkler 2.3 hardware with additional hardware options for LCD controller and relay from other 2.x versions. It will support AC and DC valves with optional component configurations and additional DC valve booster/driver. 
Board was laid out to be modular, It can be assembled with all descrete components or parts like clock/EEPROM,  LCD display (20x2) or the ENC28J60 ethernet controller can be plugged into the  headers on the board. 

Mandatory components are the power supply and SMD mounted processor. 
To convert and support DC valves an optional DC booser module is available at   https://oshwlab.com/jerry.komor/opensprinkler_2_3_dc-booster PCB that will plug into the main board into P1 connector and making it compatible with AC or DC power source. You will need to replace Triacs normally for driving AC valves with  N channel FET / MOSFETs or PNP tranisitrs.

There is provision for full size or mini SD card for logging or other uses and USB connector for programming.

To ease and help in programing and provide couple output LEDs, programming adapter is available at  https://oshwlab.com/jerry.komor/OpenSprinkler_2_3_programer-adapter
