Mainland Chinese 32-bit MCU's, MPU's and FPGA's Megathread

Is there a digikey/mouser equivalent for chips listed in this thread?

I know I can usually get ESP32s from Digikey, but from time to time one or two are export controlled and my orders get canceled - happened with xiao esp32-s3 sense and esp32-h2 devkits.

Only supplier for devboards I have used to circumvent this is the chinese seeeduino warehouse but I was wondering if there was another digikey like website.

Well ... LCSC? I mean, I haven't checked the specific chips, but LCSC is a Chinese distributor that sells a lot of Chinese and Taiwanese chips.

thanks for the reply, do we have a sub 0.5$ part for replacing STM32F030KT6? note that the pinout is not important, since we can design a NEW PCB, I need something in the 0.5$ price range with at least 32KB Flash and 4K RAM
