buzzing best 102c

Post by conquest »

i recently bought a best 102c (order number #2727350-3373711411 ) and, though it works, the control board buzzes when plugged in. when powered up it switches to a buzzing pattern instead of a constant tone. im wondering if its a defect or normal. if its defective id like a working replacement or a refund

As nobody has answered this question yet, I think you'd better send an e-mail to adafruit's customer service. I didn't use this product. So, cannot give any opinion worthwhile.

its normal! thats the heater driver which uses PWM that can be audible - let us know if the board doesn't work.
