Arduino for STM32

Update Aliexpress does not accept evidence I posted the original statement of ST to Aliexpress while in dispute. Aliexpress rejected the dispute with this words: "Evidence is not clear enough to show the problems" So Aliexpress customer service cowards spit on buyers and last aid to sell ...

Ok, I was wrong and this is great! (Trump speak mode on) The Robotdyn "Blackpill" is a pin-to-pin replacement for the "Bluepill" https://robotdyn.com/stm32f103-stm32-arm-mini-system-dev-board-stm-firmware.html So it's only black, but the form factor of a bluepill I was irritated,...

I ordered many PCB done with EasyEDA from JIlPCB. There was no single complain about the quality. Since a while JilPCB advertising full PCB manufacturing - even with soldered parts. In the past this was only available for chinese customers - maybe they changed it? I don't know, but it should/could b...

My guess is that there was a large stock of STM32F103C8, which meant that the Bluepill prices could be realized for a while. These stocks may be exhausted and manufacturers must use alternatives that are in the gray area. It is striking that the number of "bad" chips is increasing. Too bad...

Evidence is a funny game on aliexpress: counterfeit goods Please provide high-quality photographic evidence of: 1. The difference(s) between the received product and what was displayed or described by the seller. 2. The difference(s) between the fake and original items. 3. The official inspection or...

When you ask for cheap boards, you get cheap boards. Meanwhile I'm asking for a working board, not a cheap board, but I do not get it (especially "bluepill" factor) :) BTW: Are there any "plain" Bluepills available? (So without chip). This would be a temporary workaround for me ...

I don't know this was posted on this forum before:

I'm an idiot, because my project is a audio player (I sold them between 150 and 200 Euros (one piece!)). It makes no sense to save a few cents for such projects (about ~50 devices a year), but I have not faced counterfeiting in recent years. Beside that, I use more than 64kB flash - so "officia...

Yes, meanwhile the counterfeit chips are also labeled with "STM" and engraved. Aliexpress rejected my dispute, because of "lack of evidence". I contacted ST, to confirm, that the chip on my photo is a fake. Maybe they will answer. I'm done with the bluepills. And there is no trus...

interestingly the octoparts prices for the chip alone are well pricier than the pill board prices https://octopart.com/stm32f103cbt6tr-stmicroelectronics-12442975 Please don't compare consumer prices with prices above 100000+ pieces and the special deals with large number of pieces (beside special ...
