Hello, I'm the new user in this community, so I need to know if I can find an evaluation card (with STM32) to start my project. I would like to find a card equivalent to that of TEENSY 3.6 : https://www.pjrc.com/store/teensy36.html Thank you

I can also take this card for my project but it's not easy to find IDE, JTAG, SWD and also a community and a community to share knowledge.

You can choose a nucleo board. Have a look to : https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html

Example of boards with a M4 similar to the teensy36: NUCLEO_F446RE, NUCLEO-F429ZI.

The NUCLEO-L4xx (low power) or G4 (more analog peripheral) may be a good choice.

The great advantage of NUCLEO boards is the presence of STLINK, the programming and debugging probe compatible with ST tools (STM32CubeIDE, etc.). No need of bootloader => much simpler)

Go with the STM32 Discovery Board as most come with external peripherals such as LCD, storage flash, sensors, wireless communication, etc.

https://www.st.com/en/evaluation-tools/stm32-discovery-kits.html#products

This comes with WiFi, Bluetooth, external storage, lots of sensors and an STM32L4S running at 120 MHz

Equivalent in what ways?

For boards with MicroSD card perhaps some MCUDEV/TAOBAO type boards or H7 DEVEBOX or WEACT​

Hi. HBaga.1,

Thank you, in your first link I can filter my searches. I don't need WiFi but LCD, external storage (micro SD), running at 120 MHz if possible, I2S interface, Audio libraries, RTC for date/time, Digital Signal Processing, Floating Point Unit (to calculate the spectra before logging) and I think that's it all.

After entering my filters I see this component https://www.st.com/en/evaluation-tools/stm32-discovery-kits.html#products perhaps it'll be fit for my application.

Hi Nikita91,

Thank you after your link and my filters I can have this nucleo board https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html#products but I can't see the correspondence with my characteristics (LCD, external storage (micro SD), running at 120 MHz if possible, I2S interface, Audio libraries, RTC for date/time, Digital Signal Processing, Floating Point Unit) probably I will take a closer look at the datasheet.

Hello,

I'm come back again for a evaluation board, I find this mod '32F411EDISCOVERY'. Do you know if I can add an LCD display with this mod ? Thank you for your helps.

[HBaga.1]

I'm sure SPI or I2C pins are broken out on those headers, so yes, you can certainly add a basic SPI/I2C based LCD display

@DYann.1​ even if youre comming from the arduino world, baremetal stm32 programming has a veeeeery steep learning curve and you will find there is not a lot of community maintained libraries.

In other words, you probably will have to code everything by yourself, instead of sdcard.work("now");

An C++ is not the default languaje here, C is.

CubeMX has a nice mcu selector you can filter by price clock speed and peripherals

>I can also take this card for my project

it would be the easyer choice if youre not planning to build a scale procut

>but it's not easy to find IDE, JTAG, SWD

true

> and also a community and a community to share knowledge.

Last time i looked teensy had a HUGE community and supported libraries, maintained by the creator of teensy itself

Im not trying to discourage you but make sure youre not about to hit a wall by choosing stm32 over teensy without previous experience.
