What is wrong with my KK2.1.5

Well you should always flash to better FW than what comes with the board. You can get the best FW here and also an excellent manual.

Interesting, where did you supply the power to the board, on the 5v buss, or to the voltage tester pins?

to the motor 1 pins. The pin near the edge of the board is negative and next is possitive as I know. the problem is I gave 11.1v. Thank you for your reply.

do you think it would solve my problem??

Sounds like you would have fried part of the ATmel but I'd suggest you look for burnt parts, often things like diodes, transistors and cheap parts will burn first, you can replace one of those and save the board.

KK2.15 Input Voltage: 4.8-6.0V

HI mate Use a BEC or an ESC to power the KK never a lipo power is through motor 1 pins on the KK , you may have fried you board try to re flash with steveis1.8s1pro and try again to power up with an ESC you dont have to have a motor on the ESC as your only using the built in BEC

this say "EVO". but I think it is not an Evo board. So I will just flash the steveis1.8s1pro. Is that ok friend?

Look for hairline cracks, they are often harder to see.

Hi the KK 2.1.5 evo will re-flash with steveis1.8s1pro , your better off getting the flash tool and putting this on
