One of the fastest ways for a tidy printer setup to get messy is running out of ports. The BIGTREETECH Panda Hub exists for a very specific Bambu problem: you want to add one more USB-connected accessory without hanging awkward adapters off the printer or reworking the setup more than the job deserves.
That sounds minor until the bench starts accumulating add-ons. A small USB expansion accessory can be the difference between a clean modular setup and a printer that turns into a cable compromise. That gives the Panda Hub a real buyer case for GoodPrints3D, especially for P1P and P1S owners already leaning into lights, control accessories, cameras, or other small workflow upgrades.

This listing currently shows 4.7 out of 5 stars from 46 customer reviews, which is enough signal to treat it like a real buyer-intent Bambu accessory instead of catalog filler.
What this accessory actually solves
The Panda Hub solves a simple but real workflow issue: the stock printer only gives you so many clean connection points. Once you start stacking useful add-ons, port scarcity turns into friction. This accessory expands the available USB path so the machine can support another connected tool without forcing the owner into a sloppy bench hack.
That makes it strongest for owners whose Bambu printer is no longer running in bare-stock form. If the machine has become part of a broader bench system, extra clean connectivity matters.
Why this buyer case is distinct
GoodPrints3D already covers the Panda Branch power expansion board review, but that product is about power distribution. The Panda Hub lands in a narrower lane: USB expansion for accessory connectivity. That is a real distinction, not a duplicate. Buyers deciding between power expansion and port expansion are solving different problems even if both products belong on the same accessory-heavy Bambu bench.
It also sits in a different lane than the Panda Touch review and the Panda Lux review. Those are end-user add-ons. The Panda Hub is bench plumbing for owners who need the printer to support those kinds of extras more neatly.
Who this makes the most sense for
- Bambu Lab P1P and P1S owners already running one or more add-ons that compete for limited ports
- makers who care about a cleaner, more integrated accessory setup instead of dangling adapters
- buyers building a more complete Bambu workstation around visibility, control, and convenience upgrades
- owners who would rather solve a connection bottleneck with one dedicated accessory than a pile of generic workarounds
Who should skip it
- buyers still running a nearly stock machine with no real port pressure
- owners whose actual problem is power delivery rather than USB connectivity
- people buying accessories speculatively before they know whether they need more ports at all
What looks strong
- very clear problem-solution fit for accessory-heavy Bambu benches
- easier to justify than generic hubs when the goal is a cleaner printer-specific setup
- pairs logically with lighting, control, and convenience add-ons already common in the Panda ecosystem
- small cost and low footprint compared with the annoyance of port juggling
Tradeoffs worth knowing
- this is a targeted convenience upgrade, not a must-buy for every Bambu owner
- buyers should make sure their real bottleneck is USB expansion and not something else like cable reach or power needs
- the value goes up sharply only when your machine has already become an accessory platform
Where it fits in a smarter Bambu setup
The Panda Hub makes the most sense when you already know your bench direction. If you are adding more Bambu-specific gear, tidy connectivity starts mattering. It pairs naturally with pages like the Panda Touch review, the Panda PWR review, and the Panda Den review if you are turning the printer into a more complete workstation.
If your bigger issue is power distribution rather than USB connectivity, the Panda Branch review is the closer comparison. If the goal is better visibility inside the machine, jump to the Panda Lux review instead.
Editorial take
The Panda Hub earns coverage because it fixes a real operator annoyance without pretending to be more important than it is. This is not a glamorous upgrade. It is the kind of small bench accessory that becomes easy to appreciate once a printer moves beyond stock ownership and starts carrying more accessories than the original connection layout expected.
For Bambu owners building a cleaner, more modular setup, that is enough. A USB bottleneck is a tiny problem until it is the reason your next add-on becomes annoying to install. The Panda Hub looks like a sensible fix for exactly that stage of ownership.
Should you buy it?
Buy it if your Bambu Lab P1P or P1S setup is already pushing against limited USB connectivity and you want a neater expansion path. Skip it if your printer is still mostly stock or if your real need is more power distribution instead of another USB connection.

Frequently Asked Questions
What does the Panda Hub do?
It expands USB connectivity for compatible Bambu Lab printers so owners can support more accessories without relying on clumsy generic workarounds.
Is this the same thing as the Panda Branch board?
No. The Panda Branch product is a power-expansion accessory. The Panda Hub is aimed at USB port expansion, which is a different buyer problem.
Who gets the most value from it?
Owners who already have an accessory-heavy Bambu setup and want cleaner connectivity get the strongest value. Buyers with stock machines may not need it yet.
