EPA Shield

An Arduino based solution for photovoltaic and light control, used for old-fashioned but solar powered illuminated advertising billboards. Victron PV data are read by UART interface and Victron configuration is controlled by HEX protocol. PV yield and consumption energy data is sent by a SIM800 module to a central database. Values are stored and where displayed in different dashboard views. It was my first assembly project with PCBWay, there were some days communication about the manufacturing files and components (BOM, Pick&Place...) to get everything in the right format. But PCB was very friendly and helpful. I'm very satisfied with the result!
