This file is for those who want to source their own PCB and components to build their own OpenEVSE circuit board. This contains most of the features of the pre-built OpenEVSE board.
Prices subject to change and does not include taxes or shipping.
-
v2.0 - Added connections for logic level L1/L2 voltage sense board inputs and power. Changed DC-DC converter to Murata NKA1212SC with 12Vdc input. Added option for second relay. Added a header for connecting to an Adafruit color LCD shield.
-
v1.1 - Added MicroPower Direct D107E DC/DC converter. Board no longer requires a dual voltage +12V and-12V supply. Board can be powered by a simple single voltage +12V supply.
