It is probably too late. But the Arduino mega 2560 form factor would be nice.

Many people(me included) use a RaspberryPi with an Arduino mega2560 and Ramps board for 3d printing. With a meaga2560 form factor and a 3.3V Ramps board this board could be a much better solution for 3d printing. It would be better because it would replace the Arduino and the Raspberry. And it would also have much more performance on the real time part. That would help with complicated movement especially with Delta printers. Octoprint could run in the Linux section, Marlin 2.0 could run on the M4 section.

The 40-pin connector, if RaspberryPi compatible does have less than 40 GPIO and it would not be enough to drive a printer. Therefore as said in a much earlier post. More GPIO would be better !!!

From the performance point of view the most recent RaspberryPis will be much better on CPU power. So the real benefit of this CPU is the integrated Cortex-M4. And that is best for real time control stuff. And therefore the M4 needs as many Pins as possible! (GPIO, SPI, I2C, UART)

Hi Lars_poetter,

Thanks for this idea and detailed explanation.

The Mega form factor is great, it has a lot of GPIOs. If we got a second chance, we will definitely have more consideration for it.

The reason why we choose Pi form factor is that there are already many HAT in the market that suitable for industrial application. We didn’t consider Arduinos at all because we thought Arduino still gives people the impression that it is for DIYs, and not for a serious project.

We will think about how to provide more GPIOs while still make the board looks more professional in future product. Thank you!

Yes I liked it! That’s cool! When can we expect to try out the board?

We are debugging the first batch sample, and will make some amendment to it. For example, it is not easy to get the mcu with firmware already flashed for ST-Link, we may consider removing ST-Link.

If everything goes well, we can get second batch sample in September. We are considering send some free samples of the second batch to the repliers of this topic to review the board.

Thanks Jeremy! What’s the updates? Please let me know if you want me to test it out.

Hi Looking for STM32MP157C board even prototype or unfinished

@jeremy How are things coming along?

The top right corner of the first picture is the stepper motor, right?It looks different from what I saw.

Hi Yokonav,

Sorry for getting back to you late. The product was delayed to release due to some marketing strategy change. Thankfully everything starts to proceed again, I am so glad to tell you that it will be release as pre-order next week. And we will have stock in early March.

BTW, the product’s name is changed, new name is ODYSSEY - STM32MP157C. Hope you like it~

Jeremy.

Hi Kakaxiu9,

It should be the 3.5mm audio jack.

Hi Jeremy,

I do not see our last comments where you shared your email. I found your email somewhere in the online search. I have sent you an email for the free sample. Have you received it?

Thanks,
Naveen

There is a core for the Arduino IDE supporting the STM32MP1 at https://github.com/stm32duino/Arduino_Core_STM32.

The Arduino_Core_STM32 seems to be maintained now by ST.
