This is my second order of the STM32F405RGT6. The first was for ten (10) chips and all worked perfectly. This order was for twelve (12) and I have tested two and both work perfectly, like the first batch. Shipment on both orders arrived sooner than estimated and the chips were packed very well, each chip is in an individual slot within a matrix plastic holder. They are also a very good price. What more can you ask for?
I highly recommend these chips, STM32F405RGT6, from this store, kingdevil.
