Hi Doug,<br>
<br>
Has Ron released the files for that board somewhere? Because nowadays it's<br>
almost trivial to send a board spec off to a fab shop and have them made<br>
and sent back quickly and cheaply, possibly cheaper than from Adafruit or<br>
another hobbyist vendor (you may be able to buy them for roughly the cost<br>
that Adafruit does as an OEM).<br>
<br>
Having the board files available would be a boon to the robotics community,<br>
as even I (!) am now looking at STM32 boards, among them the Nucleo-64s.<br>
<br>
Cheers,<br>
<br>

Hello Doug / Murray,<br>
Are you talking about the board I created for David Anderson?<br>
I would consider that public domain if David does not mind...<br>
I can probably dig up the Eagle files for it if you don't have them.<br>
The board is shared on OshPark.com, but eagle (The tool I used for the board layout) design files might not be present?Let me know... <br>
<br>
One thing is I can't remember if I used other than basic eagle license version. I have some intermediate version that was about $800 back in the old days (circa 2010). I think there was an academic version available at the time for little money. The limitation was auto-router would not route beyond a board size of about 3"x4" or so, but you could manually route traces beyond that limit - which I did a few times way back around 2005.<br>
<br>
Getting the boards made though OshPark will be a bit expensive $72 for 3.I have used Chinese company Gojgo.com for larger quantities, but OshPark does have some deals there too...<br>
<br>
Might be other approaches building breakout boards that dock to Nucleo pin headers, but do not span entire Nucleo, if that makes sense - to reduce board square inches.? <br>
<br>
On Oshpark, search for shared project :? NucleoBot_DPA_2<br>

Ron,<br>
<br>
That's fine with me.? I'd probably chip in.<br>
<br>
Also the next-to-last version had a mistake, a pin shorted to ground.? <br>
Not sure which one is the OshPark file?<br>

In principle that Arduino shield should work for you, provided there are no<br>
issues with voltage levels. The STM32 is 5V-tolerant, so probably nothing<br>
to worry about on that end. Maybe more of a question if the Shield gets<br>
the voltage it needs. It probably will, because the arduino headers have a<br>
pin reserved for 5V. It's just one of those things worth double checking,<br>
though, before you start banging your head against the wall....<br>
Maybe more worth noting is the fact that the shield uses the L293 motor<br>
driver (not the 298). The L293 is not exactly very powerful. 1.2A max.<br>
<br>
P.S.: what happened to your plans with Pi + Ubuntu + ROS ? Is the STM32<br>
an addition to that setup, or instead of that Pi-based setup?<br>

Thanks Chris for the inputs.<br>
The STM32 is in addition to the RPi setup. Post the last update, I have not had the time to work on my RPi setup.<br>
<br>

Just made 1000 mile journey autonomously around coastline of Denmark.?? <br>
Note the use of "sparse waypoints" as we've discussed recently.<br>

Here is an autonomous boat (<a href="https://www.locarbftw.com/" rel="noreferrer" target="_blank">https://www.locarbftw.com/</a>) that I have<br>
been studying to help with the MavLink communications for my rover. Looks<br>
like a really fun project.<br>
