The "Gagaring" electronics laboratory has developed the BP-1 buffer board, which serves as a link between the drone's flight controller and various sensors, cameras, and other devices. The board solves the compatibility problem: different equipment uses different communication protocols, and direct connection to the flight controller is often impossible. The BP-1 acts as a universal interface, receiving signals from any devices and transmitting them to the flight controller in a format it understands.

One of the key functions is flight controller protection. The board is equipped with opto-isolated inputs: if any circuit fails due to a break or short circuit, the inexpensive BP-1 board will burn out, while the expensive flight controller will remain intact.

The BP-1 supports a wide range of interfaces: power outputs for dropping or detonating payloads, 8 PWM channels for controlling servos and motors, 4 UART ports for communication with cameras and telemetry, as well as CAN, RS485, and ADC inputs for sensors. The board is powered directly from the power battery (18–36 V), providing stable 5 V and 2 A for external devices. The board weighs 187 g.

The laboratory notes that the development avoids complex "duct tape" field solutions, saving engineers' time and preserving expensive aircraft.
