Cheap STM32F407VET6

Post by russian » Sun Jun 30, 2019 2:47 pm

Mouser published price for STM32F407VET6 is $11.38@1 and $6.46@1,000

eBay has 1pcs STM32F407VET6 for $4.80+$1.50 shippping = $6.30 shipped. $6.30 is below $6.46 :)

gigadevice happens to have https://www.gigadevice.com/products/mic ... 2f407vet6/ product.

Is there a definitive objective technological test to know which one you have I wonder, or is the only way to buy from a reputable vendor?
