Description

The KK2.1 flight controller is a foundational board for DIY multi-rotor builds, offering direct user interaction through its onboard LCD and button interface. Its core processing is handled by an Atmel Mega644PA AVR microcontroller, paired with an InvenSense MPU-6050 MEMS sensor for precise attitude and motion tracking. This combination provides reliable manual rate mode flight as well as an auto-level (angle mode) function for stabilized hovering.

Designed for simplicity and hands-on tuning, the board eliminates the need for a PC for basic configuration. Its firmware supports an extensive list of airframe types, from standard quadcopters and hexacopters to more exotic custom mixes, making it a versatile choice for experimental and educational drone projects. The board requires a clean 5V supply, typically provided by a BEC from an ESC or a separate voltage regulator.

Key Features

  • On-board LCD and button interface for standalone configuration and real-time PID tuning.
  • MPU-6050 6-axis IMU delivers combined gyroscope and accelerometer data for accurate flight stabilization.
  • Pre-installed firmware with support for multiple multi-rotor layouts including Quadcopter, Hexacopter, Octocopter, and custom mixes.
  • Auto-level flight mode provides attitude stabilization for easier piloting and stable hover.
  • Standard 6-pin AVR ISP header allows for direct firmware updates and advanced programming.
  • Integrated piezo buzzer offers audible confirmation of arming, errors, and low battery warnings.
  • Compact 52x52mm footprint with standard 30.5x30.5mm mounting hole pattern for easy integration.

Applications

  • DIY multi-rotor builds for education and hobbyist experimentation.
  • Stable platform for aerial photography using auto-level mode on tricopter or quadcopter frames.
  • Foundation for learning basic flight controller programming and multi-rotor mixing principles.
  • Ideal for custom drone projects requiring a simple, screen-based setup without Betaflight or ArduPilot complexity.

Frequently Asked Questions

What is the input voltage range for the KK2.1 flight controller?

The KK2.1 requires a clean 4.8V to 6.0V DC input. This is typically supplied via a 5V BEC from one of your ESCs or a separate UBEC. Exceeding 6V can damage the board's onboard regulators and processor.

What multi-rotor configurations does the KK2.1 support?

The pre-installed firmware supports a wide range of configurations including Quadcopter (X and +), Hexacopter, Octocopter, Tricopter, Y6, and even custom mixes via the onboard Mixer Editor. This makes it suitable for both standard and experimental multi-rotor frame designs.

How do I update the firmware on the KK2.1 board?

Firmware updates are performed via the standard 6-pin AVR ISP (In-System Programming) header using an external programmer like a USBasp. It is recommended to update to the latest stable firmware version as part of your initial setup for improved features and bug fixes.
