Arduino for STM32

I made a "black pill" with the F411CEU and duplicating the variant since it wasn't clear what HSE clock was the variant using... just overwriting the .id file and the clock config function (my board uses an 8MHz crystal) for what the stm32cubeide creates and I didn't have any problem so far with my ...

Yes, I like the F030 series, the ST core supports the F030F4 already, but you can easily add support for other MCU, I think that support for the F030C8 will be added on the next core release and as you already saw, the MCU's are cheap on Ali, the only downside it's the flash (mostly on the ...

Hi, 60mA seems quite a bit for a normal STM32 mcu, for a L (low power/consumption) version seems too much, maybe the problem it's on something else.

The datasheet for the STM32L476 mcu says that the power consumption it's 100uA/Mhz, that's 8mA at 80MHz. Also, the nucleo boards I think that includes ...

Try this library:

I'm using it with and F030C8 and the ST7735 display, on some of my tests I got about 10x better speed than the standard adafruit libraries

I thought IRF7103 for 3.3V control is not a good choice. Thanks for the hint with the AO3400A transistor. I checked if it is available where I live (aliexpress is stopping the project for 1-2 months), I found it. I also found AO4800, it seems to have exactly the same pin distribution as IRF7103 ...

yup the AO3400 and AO3401

Hi, I don't think so, this mosfet has already too much resistance (rdson) on optimal conditions (130mΩ). Has a gate threshold voltage at max 3v, pretty close to the 3v3 signal, so it won't work at all or it will get pretty hot. You should look for other mosfets with lower gate threshold. You didn't ...

Awesome, thanks

The power of a lighter

I tried with other ICs but I was unable to recover the bare IC, even smaller than this and the method it's too destructive
