The original KK gyro system has been updated to the incredibly sensitive 6050 MPU system making this the most stable KK flight controller board ever and adds the addition of an auto-level function. At the heart of the KK2.1 is the ATMEL Mega 644PA 8-bit AVR RISC-based microcontroller with 64k of memory.
An additional header has been added for voltage detection, so now there is no need for on-board soldering. A handy piezo buzzer is also included with the flight controller board for audio warning when activating and deactivating the board, which can be supplemented with an LED for visual signaling.
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!
If you're new to multi-rotor flight or have been unsure about how to setup a KK flight controller 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.
