im in need of USBasp AVR Programming Device to program my kk3.0 atmega board . pls suggest me need it urgently.

Hello Sir,
Although i am absolutely new to this hobby but still since i too used KK3.0 board in my quadcopter hence i fell like sharing with you. I used a USB tiny programmer(available at evelta.in) and connected my kk board ISP pins to  it through an atmega development board. Program got burnt successfully and my quad finally flies. Although you could go for a programming device on HK but i think its out of stock on it. I burnt my program through kk flashtool available at kkmulticopter.kr
Hope i would have solved your problem.
Thanking you.
Regards.

Think you are talking about HobbyKing Multi-Rotor Control Board V3.0, anyways

I had ordered from that seller for my KK 2.0 board and it works fine.

I had also ordered a 10 pin to 6 pin converter to make things easier.
