Hi. previously I have designed an omega2+ board with GPS/GNSS / GPRS support for tracking something. Then I add a pic mcu to enhance connectivity. Device has SMPS, relays, optocoupler inputs, light level sensor and temperature sensor.
I will develop software to control lighting at school.
Here is the photos.
I will write review about this project on my blog fidenetgaraj.blogspot.com
I designed another omega2+ dev board. It is still under manifacture. It has no sensor but it has additional 18 gpio.
