32bits is the future of 3D printing.
The latest marlin had ported to stm32 board,everything works, stable and smooth,have BLTouch,etc.
1)Use the easiest IDE tool that I developped for Marlin STM32 instead of arduino IDE;
2)source code link:https://github.com/hackaday3D/marlin_stm32.
3)Integrated 5 silent stepper drivers TMC2208,control it through uart.
4)Auto controlled Fan on big cooling fins shell,prevent fan from pulling in dust to motherboard directly.
5)with board monitor temperature sensor, software can control the Fan automatically and protect printed model as stepper driver will reboot while over temperature.
6)lower price than any other 32bit motherboard, almost the same as the 8bit board.


other features:

  • Support 2 extruders.
  • Highly current, support 400w big hotbed.
  • Integrate power off detector with super capacitance.
  • Highly integrated, small size.

I love those board mount XT60s but they're kind of hard to get.  Do you have a good source?

  Are you sure? yes | no

maybe you can get it fromhttps://www.alibaba.com. there are many suppliers in my city Shenzhen China.

  Are you sure? yes | no

Thanks I'll look there.  I got a few from aliexpress last time.  But at that time I think I only found one supplier and it took a relatively long time compared to other things I buy from china.  I think it took 5-6 weeks.

You find them easily in an rc toys shop - they are very common in planes and any copters.

Hey! That's really nice form factor too. I was also working on doing something similar on my project but now has evolved to something entirely different. What are you heatsinking in the bottom? 

Also If you'd like to collaborate or need any form of help, feel free to message me and also check out my project. 

All the best!

Thank you for the like! and I am very interesting to your 3+Pi project!

  Are you sure? yes | no

the 5 tmc2208 run very hot! so the heatsink and fan are needed.The board is designed again for the high hot.

  Are you sure? yes | no

Amazing work! May I ask which motherboard this is, and where the motherboard can be purchased? Also, which firmware was the motherboard designed for?

  Are you sure? yes | no

Thanks! the final board will be coming soon! and before that we will send severval board to test

  Are you sure? yes | no
