“Vernier Circuit Board 2 Recall: Burn Hazard from Overheating Switches.” GovInfoNow, updated October 11, 2026. https://govinfonow.com/recall/3569-vernier-circuit-board-2-recall-burn-hazard-from-overheating-switches. Based on CPSC recall #8340 (https://www.cpsc.gov/Recalls/2018/Vernier-Software-Technology-Recalls-Circuit-Boards-Due-to-Burn-Hazard-Recall-Alert).
Why it’s dangerous
The hazard arises because two switches on the board can get stuck between positions, leading to a short circuit. This electrical fault causes the switches to overheat, which in turn makes the metal case of the switch become hot enough to pose a burn risk to users.
Who’s affected
Students and educators who purchased the Vernier Circuit Board 2 directly from Vernier, by phone, catalog, or dealers between August 2015 and April 2018. While no injuries have been reported, anyone using this specific educational tool is at risk of burns.
How to tell if you have this one
Look for a green-colored circuit board measuring 10 inches wide by 6.5 inches high. Check the upper right corner for the Vernier name, logo, and order code VCB2. Verify the revision marks printed below pins 35, 30, and 31 on the lower section; recalled units will show 'VCB2 REV 1 PPRL 2015' or 'VCB2 REV 1A PPRL 2015'.
