      Will expansion board be available simultaneously with this one?

        @Mosher We have prototypes of the expansion board as well and plan to have the production version them available for sale at the same time the production version of this board is available.

              That is the intention, however it's one of the few hardware features of the board that I haven't yet written the firmware support for.

              @dc42 do you mean support for the Neopixel backlight specifically or the MiniPanel itself? Because you're welcome to use the code in my fork of RRF3 for the MiniPanel support. I've been using this build successfully for many weeks now. I suppose that even if the Mini 5+ hardware side changed a bit, my work could still save you some time.

              BTW, I'm also interested in beta testing the new board. I have this 'gift' of being detail oriented and noticing issues. Also curious to find out if the TMC2209 drivers will better cooperate with my steppers compared to the TMC2224 drivers on my Maestro.

              Creality CR-20 Pro with a Duet 2 Maestro, 3Dfused X+Z-axis rail kit, HIWIN-based DIY solution for the Y-axis, E3D Hemera, working ST7565 MiniPanel and various other small hardware improvements.

                I can’t wait to test this baby!
                I’m so excited to see how the TMC2209 perform compared to the TMC2260 with RRF.

                    One more question: will GPIO14/15 on the SBC interface be wired to a UART on the µC? Seems like this is not the case in the moment for the Duet 3 but could be very useful for compatibility with Klipper.

                      No; but a UART is available on the IO1 connector.

                        @dc42 I guess there is no space left for a 2x2 header to jumper this connection if needed?

                          @pixelpieper can you expand on the usage? Why can Klipper not use SPI?

                            @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 🙂

                                      @pixelpieper then you might want to change the wording - asking for additional space for a 2x2 header isn't the same thing, and doesn't even achieve the goal of using the same 26pin ribbon cable without custom wiring loom.

                                        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

                                            if its talk of a unpopulated headed then solder bridges are smaller and easier to place?
