As many of us noticed all recently purchased Turnigy Plush ESC (10A in particular) are a little bit different now. They have slightly bigger length of the board and are based on a totally new microcontroller, which is now SIL F334 instead of good old ATmega8.
I don't know yet if that's a good thing or not, but one thing for sure is that they cannot be modded anymore using firmware which was written for AVR (like for instance conversion to I2C instead of PWM).
Another interesting observation is that Turnigy Plush 10A and Exceed Proton (former Volcano) 10A ESC are exactly the same, I mean everything, including the board version HW1 33V2.0 and all components, as you can see on the attached pictures. The only difference is that Plush has two 5V 1A voltage regulators stacked on top of each other, giving the 2A BEC rating, and Proton has just one regulator with corresponding 1A BEC rating.
Oh, and wires are blue on Proton.
