The Vernier Circuit Board 2 (VCB2) includes all of the components that are included on the Vernier Circuit Board (VCB, discontinued) with the same pin numbers, with the following additions:

47 kΩ resistor
1 uF capacitor
5 mH inductor with powdered iron core (available separately as Inductor (IND))
buzzer
1 kΩ linear potentiometer

Any Vernier lab activities that require the Vernier Circuit Board can be done with the Vernier Circuit Board 2, with no change to the instructions, since the pin numbers are the same.

The Vernier Circuit Board 2 also offers different power options than the original Vernier Circuit Board. Instead of 3 V provided by two D cell batteries, the Vernier Circuit Board 2 uses up to 4 AA cells, with access to one, two, three, or all four providing potential difference. The Vernier Circuit Board 2 can also be powered by the LabQuest^® Power Supply (LQ3-PS).

Instead of having post terminals for connecting external power or components, the Vernier Circuit Board 2 has speaker-style spring clips which allow bare wire connections or alligator clip connections.

The Vernier Circuit Board 2 also has space for an optional breadboard, size 170PT, 1.75×1.40in.
