Figured I'd start a thread for these.
First, the best resource possible is Sidehack's USB hub thread:
https://bitcointalk.org/index.php?topic=1779423.0Things to look for on the hub:
- Provides at least 1amp per port
- Has a way to hook up to your Pi/PC (this is sometimes described as "Sync" not just charging)
Here's my learnings from playing with those that also apply to the Moonlander.
Budget Hub for 3 or fewer MoonlandersPluggable USB hub -
https://www.amazon.com/gp/product/B00L2LK164These have 3 voltage regulators that are shared by the ports next to each other, so you can only run at max 3 of the Moonlanders. Put one on port 1, port 4, and port 7.
Hub for 3-10 MoonlandersSipolar 20 Port -
https://www.amazon.com/Sipolar-Industrial-Charger-Refurbish-Cellphone/dp/B01KPOEX9OThis hub can power up to 12 moonlanders, due to the size of the fan. It has two USB 3 ports to connect to your PC or Pi, so be sure you plan that. Some people reported having trouble getting the Pi to recognize it, but if you have this issue, plugging the USB3 from this into a cheap USB hub (like an Amazon basics 4 port USB2 hub) and then that into the Pi works.
Other hub:
