UUGEAR Mega4 4-port USB 3.1 PPPS hub for Raspberry Pi 4B · 模型 30977
Mega4 is a USB HUB for the Raspberry Pi 4 that can be powered externally. It is great for robotics applications, because it allows plugging hungry components without overloading your Pi. See https://www.uugear.com/product/mega4-4-port-usb-3-ppps-hub-for-raspberry-pi-4b/ I could not find online any drawings or CAD models for this component, even after contacting the manufacturer, so I made a simplified, approximate model myself based on manual measurements. This model is only suitable to assist on mechanical design. E.g. most electronic components are missing as well as several of the board contact terminals. On the other hand the positions of the assembly holes and USB connectors is relatively accurate. Note that when the Raspberry is mounted on the provided 10mm standoffs, the USB bridge seems to be about 1mm too short, i.e. the male and female connectors appear to be mounted on the board about 1mm too close together. However it is possible to plug the bridge pushing a bit despite the interference, making the board flex a bit. I don't know if this is by design - for a snugger fit - or it is a matter of tolerances of the unit I used for measurements. Feedback is appreciated as this is the first model I upload to GrabCAD. Created with FreeCAD. Model provided as is, without guarantees of any kind. I hope it helps!
