An abbreviation for non-volatile random access memory, a type of memory that offers the fast read and write speeds of standard RAM while retaining its data when main power is lost. This is typically achieved by backing standard SRAM with a small coin-cell battery or by using specialized flash-based architectures.
The system configuration is saved to NVRAM, so check the coin cell battery if the board keeps losing its settings.
