Re: stm32f030f4p6
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 F030F4-1...

Re: Clock frequency change
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 ...

Re: Nucleo-F030R8 and ILI9341 Changing SPI Speed
Try this library:
https://github.com/Bodmer/TFT_eSPI
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

Re: IRF7103 and 3.3V control with STM32
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. Th...

yup the AO3400 and AO3401 http://www.aosmd.com/pdfs/datasheet/ao3400.pdf http://www.aosmd.com/pdfs/datasheet/ao3401.pdf are very attractive searches like this returns lots of entries https://www.aliexpress.com/wholesale?catId=0&SearchText=ao3400 https://www.aliexpress.com/wholesale?catId=0&...

Re: IRF7103 and 3.3V control with STM32
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 ...
