3:22 I think that's the NPU. The BTT pi v2 is listed as only having 1 mali GPU core with a rockchip SoC, so that 1 core is part of the CPU chip. That would mean the separate chip is an NPU for spaghetti detective like activity(computer vision) which is fine at the .8 TOPs listed, but keep in mind that it'll heat up. it's essentially one of the newer Chinese "NPUs" which are just repurposed cheap/ugly CPU cores and some memory.
They are using the RK3566 chip which comes with an NPU by default. It doesn't do much for this installation but they probably just decided to market it. Any acceleration would need to be done through the RKNN library so not all models work out of the box which is a minus. It's not "repurposed CPU cores" though.
Really wanting to update my mcu board on the swx2 just not sure which one. I have your pcb board and am wondering if it has an extra 5v so I can install knomi 2 with the stealthburner upgrade im working on. I can honestly say I'm not ready to give up on the slingers and not ready to get on the bambu train yet.
I love the board overall but I believe that taking out tx & rx for uart is a big downgrade and secondly just why. I was wanting to have a cleaner setup with less big wires and save some usb ports for other stuff kind of a letdown.
@@TheFeralEngineer I saw a post somewhere on reddit about that but I couldn't get it to work I even adjusted the armbianEnv file with no success. Maybe I was missing something idk. On a side note wouldn't this mess with your display if you are running one?
@@nickolascuartero7854 it's a little unclear when modifying the armbianenv file. You need to put all of the device tree overlays you want to open up on a single line, you can't just uncomment uart5 somewhere down the list, you need to put it in the first overlay line that is uncommented. Also, it's important that you also have a ground connected. I didn't run into any display issues, but I'm currently running mine headless and connecting to it through a btt pad7 with a wireless connection set up in Klipperscreen.conf
@@andyw8009 Even with the Pi 1.2, the U2C board would have to be purchased separately so you need to buy extra hardware to run CANBUS on ether board. The smaller U2C board that plugs directly into the 1.2 board is a cleaner install option and it is too bad they couldnt retain that option.
@@EtherealProject3D I thought it was supported as it is on the Manta boards with no other component needed, turns out it does need the U2C board you mentioned, my bad ;) perhaps this is why they dropped it.
@@varazir Not on the old BTT Pi, I had the display on an RPI4 but I dont use it much so I moved the display to this machine after getting the new BTT Pi V2
