Vernier Circuit Board 2 (VCB2)
Specifications and User Guide

This article is about the Vernier Circuit Board 2, introduced in late 2015. Information about the original Vernier Circuit Board can be found at Vernier Circuit Board (original model) Troubleshooting and FAQs

-Make certain that the Power Source Switch (SW1) is set to the correct source of power that you are using. If you are using AA batteries, check that they are charged.
-If your circuit appears to have no power, especially when using more than one battery, make sure that the batteries are making contact with the battery holder. If the battery is resting at a slight angle, the battery might not be in electrical contact with the circuit. Pinching the sides of the battery holder or pressing the battery flat will typically fix this issue.
