Electronic Modules
The electronic modules developed at LVNT are boards dedicated to specific functions that make up the control architecture of unmanned vehicles. They concentrate circuits and interfaces responsible for tasks such as navigation and communication, allowing each vehicle subsystem to be handled in a modular way. This approach also supports standardization, the reuse of components in different projects, and the continuous evolution of the hardware.
Optical Communication System for Underwater Applications (2022)
This is a unidirectional prototype that uses high-power LEDs and a high-gain silicon photomultiplier to establish communication with a bandwidth of approximately 2.4 Mbps over distances of a few meters. It has a TCP/IP-compatible Ethernet interface for sending and receiving data through the transmitting and receiving units.

Electronic Telemetry Module (2020)
This board is mainly intended for communication between the vehicle and the command station. Its main component is an RF modem operating in the 900 MHz band, with a transmission rate of up to 276 kbps and a range of up to 60 km when using a high-gain antenna and operating without obstacles. As additional resources, it includes a GNSS receiver for vehicle geolocation, a GSM/GPRS module for long-distance data transmission within cellular network coverage, and a microSD card slot for data storage. All these modules are connected through UART communication buses to an ARM-core microcontroller, which can be programmed according to the user’s needs. Communication with other boards can be performed through two independent CAN buses.

Electronic Battery Management Module (2020)
The BMS board is responsible for conditioning the battery packs, managing the energy supplied by them, and ensuring protection against overload and short circuits. The board has independent inputs for up to four battery packs, a Hall-effect current sensor, a voltage sensor, a temperature sensor, and semiconductor switches that allow each pack to be turned on and off independently. The entire management of the BMS board is performed by an ARM-core microcontroller. The board also has a CAN communication bus that enables communication with other boards within a system.
