(1/12) > >>

DavidAlfa:
Found a new company making stm32-like chips on AliExpress
https://a.aliexpress.com/_ujJBWl

Specs are pretty nice:

Air32F103
216MHz, 32K RAM, 128K Flash
https://chowdera.com/2022/198/202207171843163101.html
https://wiki.luatos.com/chips/air32f103/index.html
(Actually the RAM can be unlocked to 97KB!)

Air105
204MHz, 640KB SRAM, 4MB flash

pcprogrammer:
Not cheap though for the AIR32F103 that is. ~10 euros shipped :palm:

thm_w:
What I don't get is they claim "compatible STM32 For Arduino". But the screenshots are showing Keil, and the AIR105 is clearly a completely different beast from the STM32F103.
I guess the AIR32F103 is the only compatible one then? and AIR105 has no STM equivalent at all.

There are also more in your link, AIR101, AIR106

If the 32F103 is a drop in compatible replacement, then its a smart way to enter the market. As gigadevices did.
But all of the non-GD clones, from what I've seen, haven't been as good in terms of compatibility. Even the GD one isn't perfect.

Here you go, $2: https://www.aliexpress.com/item/1005004606391844.html

edit: the AIR103 module is not the same pinout as bluepill, or blackpill, is it compatible with any pinout? Don't know what these people are thinking, just use an existing pinout. Completely worthless board now.

For me this one is ~4 euros shipped, which is comparable to others, but with 216MHz compared to 72MHz much faster. Is it reliable though?

But with a pin out of the board that does not match the bluepill it becomes its own thing and not a drop in replacement for something you already made. For me as a hobbyist not a problem, but already have enough development boards lying around :-DD

DavidAlfa:
Who buys bluepills board for professional products...?
It's all for hobbists.
