	KK2.15 Multi-rotor LCD Flight Control Board Atmega644 PA Main Chip for Multicopter No Shell
	
	The original KK gyro system has been updated to an incredibly sensitive 6050 MPU system making this the most stable KK board ever and allowing for the addition of an auto-level function. At the heart of the KK2.1 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional header has been added for voltage detection, so no need for on-board soldering. A handy piezo buzzer is also included with the board for audio warning when activating and deactivating the board.
