Open-BLDC V0.1 Fully Assembled

3 Replies

I finished soldering Open-BLDC V0.1 boards and took some pictures while doing so.

After connecting it to the power everything seems to work properly and nothing is burning. That is really good news.

One little thing that is bothering me. The board draws 60mA, what is a value that I expected. The 5V linear regulator gets really warm. I am not sure if that will be a problem or not. But I did not find any other problems or screwups yet, even the big MOSFETs can be soldered using a simple soldering iron. It takes some time though, because the board and the MOSFETs are monstrous heatsinks.

More news coming up as soon as I start playing around with the software.

Open-BLDC V0.1 is alive!

I assembled the basic STM32 circuitry of Open-BLDC and it works. I also made a video showing the logic board and blinking around. I know it is a bit pointless but I love blinking LED’s! 😉 I wrote the software using libopenstm32.

Have fun:

Video on Youtube and here the same video on Vimeo.

While assembling Uwe and I made some photographs that I don’t want to hold off either.

Good news everyone! The Open-BLDC boards are on my table. If you ask me they look gorgeous. 🙂 But decide for yourself …
