BEFORE UPGRADING FIRMWARE:
1) make sure you check latest pdf manual for changes (change log)
2) note that firmware 11+ is for boards with improved CP signal check (see revision 11 details)

4) if sometihng fails be ready to recover original EVSE firmware using PicKIT (can buy from farnell.com and search "pickit 4")
