DescriptionThe next evolution of the rotor revolution is here!!The KK2.1 is packing new found power with updated sensors, memory and header pins. Designed by the grandfather of the KK revolution, Rolf R Bakke, the KK2.1 is the evolution of the first generation KK flight control boards. The KK2.1 was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts. The LCD screen and built in software makes install and setup easier than ever. A host of multi-rotor craft types are pre-installed, simply select your craft type, check motor layout/propeller direction, calibrate your ESCs and radio and you’re ready to go! All of which is done with easy to follow on screen prompts!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.If you’re new to multi-rotor flight or have been unsure about how to setup a KK board then the KK2.1 was built for you. The 6 Pin USBasp AVR programming interface ensures future software updates will be quick and easy.Specifications:Size: 50.5mm x 50.5mm x 12mm Weight: 21 gram (Inc Piezo buzzer) IC: Atmega644 PA Gyro/Acc: 6050MPU InvenSense Inc.
