Description
A portable analog/digital trainer board is a comprehensive, self-contained educational tool for circuit design and testing, typically featuring a large solderless breadboard (often >1600-2800+ tie points). Key specifications include fixed (±5Vplus or minus 5 cap V±5)and variable (±15Vplus or minus 15 cap V±15 or 0−30V0 minus 30 cap V 0−30) DC power supplies, a built-in function generator (1Hz−100kHz+1 cap H z minus 100 k cap H z plus1−100+for sine/square/triangle waves), logic input switches, LED indicators, pulse switches, and potentiometers.Â
