Board Gen 3 V1c with regulator mod for esp8266.
History is that I had this in a prius inverter with an Outlander rear motor and i experienced some issues that gradually over time got worse until the car became untrustworthy. At that point i pulled the prius bits and went vcu.
I never did ascertain if the fault was with this board or else where so sold as seen. It fires up and programs ok but further than that i can't say
