Processor: Atmel ATmega644PA 8-bit microcontroller. Sensor: InvenSense MPU6050 (3-axis gyroscope and 3-axis accelerometer) for stable flight and auto-level function. User Interface: Onboard 2.1-inch LCD screen and five buttons for configuration and field tuning. Input Voltage: 4.8V – 6.0V (typically powered via a BEC from an ESC or receiver). Compatibility: Supports a wide range of multi-rotor layouts (e.g., Quadcopter , Quadcopter X, Hexcopter, Y6, etc.) and allows for custom mixes via a mixer editor. Setup: Comes with pre-installed firmware (often V1.19S1 OpenAeroVTOL or similar) and offers an easy, on-screen guided setup process. Audio Warnings: Includes a piezo buzzer for audio notifications when arming/disarming the board. Programming Interface: Features a standard 6-pin AVR interface for future firmware updates
