Genuine stm32f103c8t6 blue pill sources

[arpruss]

I thought I'd start this thread for people to list trustworthy sources they have found of genuine stm32f103c8t6 blue pills.

To start things off, I ordered 6 units in February 2023 and 8 units in September 2023 from the TZT teng official store on Aliexpress: https://www.aliexpress.us/item/2251832533365278.html
Make sure you click on the item that shows "stm32f103c8t6" and says "original chip".

All 14 were genuine according to Blue Pill Diagnostics 1.640. The pricing was good, and the latest order shipped from the USA, and came in about two weeks.

It isn't always worth it to have a genuine chip.

Agreed. I have some working projects with fakes. But I've also seen problems with fakes: delayMiicroseconds() being off by a factor of two and the RTC not starting.
