KK2.0 Multi-rotor LCD Flight Control Board

The KK2.0 represents a significant advancement over the initial iteration of KK flight control boards. Developed with a focus on accessibility, this iteration was meticulously crafted to democratize multi-rotor flight, extending its appeal beyond seasoned experts. Featuring an intuitive LCD screen and integrated software, installation and setup have been streamlined to facilitate ease of use. Users can effortlessly select their desired craft type, verify motor layout and propeller direction, calibrate ESCs and radio, all guided by clear on-screen prompts.
Noteworthy enhancements include the integration of a highly sensitive dual chip 3-axis gyro and single chip 3-axis accelerometer system, elevating stability levels and introducing an Auto-level function. At its core lies an Atmel Mega324PA 8-bit AVR RISC-based microcontroller, boasting 32k of memory. Additionally, two additional motor output channels have been incorporated, allowing for control over a total of eight motors (Octocopter). To complement its functionality, a Piezo buzzer has been integrated to provide audible alerts during board activation and deactivation.
For those new to the realm of multi-rotor flight or seeking clarity on KK board setup procedures, the KK2.0 emerges as a tailored solution. Its 6 Pin USBasp AVR Programming interface ensures swift and straightforward execution of future software updates, reinforcing its commitment to user convenience and adaptability.

Flight Performance

We anticipated the performance of the KK2 board to be satisfactory yet not exceptional; however, we were pleasantly surprised by its remarkable stability. It stands out as the most stable board we have evaluated thus far, achieved within a mere setup time of approximately 10 minutes. Furthermore, its maneuverability exceeds expectations, proving to be notably impressive. The controller instills a sense of control and confidence, as it operates smoothly without any undesirable or unexpected behaviors.
Adjusting the proportional-integral (PI) values is a straightforward process with minimal associated risk. Even when operating at high P-gains, the drone maintains stability without succumbing to sudden oscillations, a phenomenon that can occur with other controllers when sensitivity levels are calibrated for hovering but prove excessive for high-speed flight.
The auto-level feature offers customizable settings, allowing users to adjust the response from gentle to sharp as per their preferences. Additionally, the optional height dampening function can counteract the loss of lift during pitch or roll maneuvers. However, this feature may be unnecessary for pilots with moderate experience, as they are accustomed to modulating throttle while maneuvering. Nonetheless, it provides an additional layer of functionality for those who may require it.
