openinverter forum

Had some time and decided to start soldering the Gen2 OI board.

Please bear with me as not totally tech savvy but will have a go. I have searched on the forum and will first before posting question.

Stupid Q1.

OI all soldered up, Which way round does the mini mainboard board fit onto the main board ?
Johu original pic has his original version , not the newer one.

Is Pic1 or Pic2 correct orientation ?


While I had the soldering stuff out decided to fit the Smd parts to the Zombie that I have putting off for so long, quite a achievement for me as have only ever fitted through hole parts.

Did take a few attempts before getting it right.
Thanks in advance

Wish I benched tested it before refitting to invertor, resealing and refitting back on top of motor !!

Stupid Q2 - I can set this up (syncof) with just 60vdc HV ( 5x 12v batteries ) ?

Stupid Q3- Can someone link me the latest software version for the mini Board ?

Thanks
