No significant difference.
They both seem a bit pricey, though. For the same amount of cash, you can get 10 of them at ebay.
this may be true, but if you buy one, you have full access to data sheets and a forum to ask.
I have a growing box of parts from e-bay that have no support, no wiring diagram and the supplier had the kindness to reduce the shipping weight by removing all that heavy ink on the chip.
I am hesitant to ask if anyone knows what chip it is. it has 14 pins and is black. it has a little dimple in one corner. (anyone ?)
also, my luck has been pretty good, about 80% of the stuff works. it would be a pain to order 10 parts, have no clue how to connect, then struggle with getting them wired correctly only to finally figure out it did not work in the first place.
once you get that good one to work, and you need 10 more.......
