kk 2.1 Flight Controller Board

Product Description

One of the more popular multirotor controllers, the KK2, has undergone a number of changes for the better. The updated KK2.1.5 features an updated gyro system with a very sensitive 6050 MPU system. It also uses an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. Installation and setup are easier than ever, thanks to the large LCD screen and built-in software. To top it off, the KK2.1.5 has built in polarity protection and a fused output for the included buzzer.
The KK board has always been known for its simple setup, making it perfect for FPV multirotor operations. Hopefully, the dreaded gyro drift issues that plagued the original have been eliminated with the KK2.1.5
