I have a basic EVSE with no display for sale. It auto detects L1 at 12A or L2 at 16A. It is mounted in a rugged electrical junction box. The basic box is waterproof but I have not paid attention to waterproofing the holes. There are no open holes but I would consider it splash proof at best. It has a 14 gauge GM Voltec coil cord. It stretches to at least the length of my 25 ft Leviton cable. The input cable has a L6-20p installed.
The unit is based on an Arduino Uno with a OpenEVSE shield built on a prototype board. There is a separate line detect board. The serial and I2C pins are brought out on headers. It is programmed to version 2.0B7 with CLI enabled.
I have been using this all week to burn it in. It works flawlessly but it is sold ASIS. I guarantee it will work upon receipt.
I am selling this for $275 plus $25 for shipping. Local pickup in Anaheim near Disneyland is available. Payment is by Paypal if I ship or cash for local pickup.
I have a L2 to L1 120V adapter for an additional $20.
Thanks pchilds for the case idea. It is truly a tough box.
