Thought it might be useful to post a pin layout of the Hobbyking 40A SBEC esc flash pin pad layout for flashing of the Simonk firmware.
I used a digital multimeter to confirm which pins are which, and are shown in the photo below. Only my rough notes, sorry, didn't take a photo of the actual esc board. Although I can say that the pads are in the middle of the esc, rather than on the edge like a lot of the youtube videos show.
Anyway, hope this helps someone!
PS, I have put red heatshrink on the esc after having to cut it open, it's original heatshrink was black.
