The DIY v4, v4.2 and v4.21 were not official OpenEVSE products. They were designed by an OpenEVSE builder to be compatible with OpenEVSE code and contained some re-designed circuits. The design is older, not up to standard of the current boards and does not support current monitoring. The archive of the project is here: https://code.google.com/p/diy-openevse/ 


The current board available in the OpenEV store is the OpenEVSE PLUS v4 which does support current measurement and LCD.


Hi,

is the DIY_OpenEVSE_PLUS git official OpenEVSE product? and is it  in sync with v4?


Thanks

Yoav

DIY_OpenEVSE_PLUS git was a official product a couple of years ago. It is equivalent to the v2.5. From the v4 it is missing the diodes on the AC_Detect and the IEC proximity pilot circuit.

tnx! i see also that it based on ATMEGA8 and not ATMEGA328P

It is the DIP version of the 328P, the schematic used a generic footprint.

Hi,
R12 and R13 in the pilot circuit use to be 2.5k and R1 1K at 1%
in other versions i see R12/13 2.4k and R1 650oms or in version 4 620oms.
I'm about to order parts from digikey so what is the recommended values and do i need 1% tolerance or any 1/4w 5% will do?
