I have not tried them yet but no reason to doubt that they will work. It is a shame that the supplier has not updated the images on Amazon though. The supplied product is different visually and in an inferior way. The pins no longer have identification text and, just to add to possible causes of confusion, the capacitor numbering has been reversed. It does not take much effort to work out with your thinking head engaged but - equally - it does not take much effort for the seller to update the product images either.Also - It is NOT a buck converter - the AMS117 device is a linear regulator. But hey we are all used to online descriptions being wrong as a normalised thing.

3.3v欲しさに買った、他意はなかった。ジャンパーワイヤー付いてるのはちょっぴりお得か。

Arrived promptly, good price. The description says it's a buck converter - looks like a linear regulator?
