Customer Reviews
I've had the pleasure of using the Octopus Pro v1.1 from BigTreeTech, and I must say, it's one of the best 3D printer controllers/motherboards I've encountered. As an engineer and electronics hobbyist, I can truly appreciate the thought and effort that went into this product.
First off, the feature set is impressive—BigTreeTech has packed this board with everything you could need for a custom or DIY 3D printer. The "Pro" in the name is fully justified, as it goes above and beyond what you'd expect from a standard controller.
The PCB design is nothing short of amazing. From an engineering standpoint, it’s clear that the team at BigTreeTech has done a remarkable job. The layout is clean, the components are well-organized, and the overall build quality is top-notch. The STM32H723 MCU used in this controller is particularly noteworthy. It’s a highly capable and powerful chip, making it an ideal choice for running along with Klipper firmware, which I've found to be perfect for pushing the limits of my 3D printer.
On a practical note, I received the product on time, and it arrived in perfect condition—nothing was damaged during shipping, which is always a concern with sensitive electronics.
I want to emphasize that this is not a paid review or paid promotion; these are purely my personal opinions based on my experience with the product. The Octopus Pro v1.1 has genuinely impressed me, and I highly recommend it to anyone looking for a reliable and feature-rich controller for their 3D printer.

Once I got it all connected and flashed it is working awesome. Definitely download the pin out image and manual from GitHub.
Perfect and fast board for core xy printer. Has as well lots of ports for additional upgrades. I love the separate power Selektion for each 2 pin output.
BIGTREETECH BTT Octopus Pro V1.0/V1.1 For 3D Printer
I would wait to do a review but with all the other ducks I have, the main board will work as intended I'm sure, I have 2 skr minis e3 v3, both are the nest thing I ever got, I added the sfsv2 to both amd made it better, also the btt pis v1.2s just mad the printers rock, so when I add this board to one of them to handle triple z?
