The KK2.1.5 Multi-Rotor LCD Flight Controller Board is a high-performance and feature-rich device designed to provide precise flight control for multi-rotor aircraft, particularly quadcopters. Equipped with an Atmel Mega644PA 8-bit AVR RISC-based microcontroller and an MPU6050 gyro/accelerometer, this flight controller offers exceptional stability and responsiveness during flight.  It comes preinstalled with the KK 2 firmware and features advanced processor technology from STMicroelectronics, sensor technology, InvenSense system delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle. A handy piezo buzzer is also included for audio warning when activating and deactivating the board.

The LCD screen and built-in software make install and setup easier than ever. The 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 KK 2 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory.
