Duet 3 Mini 5+ : Initial announcement
-
@T3P3Tony Klipper could if someone implements it, direct UART communication is just already available and would simplify the implementation.
If you have the space to allow for a 2x2 header to be soldered in connecting to the IO1 pins it would be a neat way to get this UART (edit: connected through jumpers) if needed while adding no cost to the PCB...

The connector that support PanelDue already has UART available and as of 3.x something RRF support using it in "raw" mode so that can be done as is for all Duets.
-
@bearer sure, its just much neater if it can be done directly through the already existing SBC cable rather than having to make your own wiring loom.
-
@pixelpieper oh, then i missread your post, as adding UART to the SBC connector only requires to route the rx and tx pins to pin 8 and 10 on the existing 2x13 header
-
@bearer hence the suggestion to allow for this connection

@bearer @pixelpieper
Thanks - I understand. The 2x2 header would be a pair of jumpers so that the UART was not always connected to the SBC (for example if you wanted to use a PanelDue instead.
I will look at this as part of the next design review.
-
@bearer good point, I meant 2x2 in order to add jumpers to RX and TX
-
d'oh - brain is being slow...
if its talk of a unpopulated headed then solder bridges are smaller and easier to place?
-
So if I have a Duet2wifi with 1.68A steppers for X Y E0, Dual Z 1.68 steppers in serial, bltouch and Rotating Magnet Filament Monitor, I could go to this board without issue ?
-
@bearer either through bridges or by soldering in the header and adding jumpers to easily reverse it, I don't mind either way.

most likely quite soon, ref https://forum.duet3d.com/post/168488 (maybe i missread that too, I meant you could use existing board with klipper and sbc)
-
@pipersw You would probably use a separate driver for each Z, but yes.
-
Wow. This is going to be a release day purchase for sure. I love my Duet2 Wifi and have put RRF on my SKR boards because the Duet spoiled me so much with its ease of use.
I was reluctant to buy more Duets as I figured there'd be something like this coming soon.Can't wait. I'll take two!
-
Very excited about this with the three driver expansion board!
I've been deliberating what board I want to use for an upcoming project and the Duet 3 6HC was up there, although a little ott for my needs.
@gregsaun pointed out this upcoming board and it's actually a perfect match for the project. There is no longer any question as what board I'll be using -
100%
all day -

... that green PCB confused me for a second.
Exciting!
-
It's only green because green prototypes are sometimes faster to get made and delivered than blue ones.

@dc42 Want one for my Delta time it had an upgrade lol
