content: Hello to everyone.I'm trying to assemble my DIY cyberdeck. Below you can see what are the main components that I have chosen. For example the Radxa Zero 3W as a main board,as keyboard I've chosen the CardKB,as "mouse" the Circle Trackpad.Taking in consideration that the Radxa Zero has one only USB-C port for transferring data,what I need is an HUB to connect to that USB-C port at least the trackpad and the keyboard.The trackpad works because it is connected to the Svlinky controller that ends with a USB-C female connector. The keyboard should be connected to the Radxa through its Groove to USB-C cable that ends with one USB-C female. Now,I want to connect these two USB-C females to the Raxda board.On Aliexpress I found the HUB that fits perfectly on the space available but it's not good for the trasferring of data.It offers two USB-C male,one on the left and one on the right to connect the trackpad and the keyboard and one USB-female to get the power from the Radxa board. I would have connected one USB-C to USB-C male converter to attach the HUB to the radxa board. It's a shame that it will not work.Aanyway,it is not even perfect. What I'm looking for is an HUB with 2 USB-C male port (one for the keyboard,one for the circle trackpad and one USB-A FEMALE port for the dongle WI-FI. Or maybe an HUB with 3 USB-C female ports. And I will use an adapter USB-C (male or female ?) to USB-A (female) to connect the Wi-Fi dongle.I'm sure that the HUB that I'm looking for exists,but It seems hard to find it at least for me....because it should be small,since I have a very little space available inside the case...please help me.PS : no soldering.

content: The Type-C connector that is used to power the board can be split into charging + USB2 data using this adapter:https://nl.aliexpress.com/item/1005007245796549.htmlor use an in-line Type-C hub like this:https://nl.aliexpress.com/item/1005007514920868.html

content: They are not good because I need more USB-C ports. At least there should be two of them. If I use the hubs that you have suggested,I should add two converters from USB-A to USB-C. At this point it (they) will occupy too much space inside the case.Basically what I need is a USB-C port only (or mostly) compact hub. Because I have 2 usb-c ports (keyboard and trackpad) and 1 only usb-a (wifi adapter). With 3 usb-c ports I will use one only converter from usb-a to usb-c. Plus the usb-c port used to grab the power from the radxa and give it to the attached devices.

content: Thank you again for all the help you are giving to me. Unfortunately the USB-C hubs found by you aren't good for my layout because they have a cable. I'm building a phone,I have a small space inside the case of the phone. Those rigid cables are too bulky.
