USB 2.0 docking station based on SL2.2S/SL2.1A

I. Portable WiFi Version (SL2.1A)
I wanted to make this docking station because I needed it myself. Every time my computer connects to the portable WiFi and then uses Bluetooth on my computer, there's severe latency and lag. My computer only has three USB ports, and after connecting the keyboard, mouse, and portable WiFi, there are no extra USB ports available. I didn't want to buy a new docking station. Therefore, I wanted to modify the portable WiFi into a mobile WiFi docking station.
Traditional docking stations use USB interfaces, but since our design will be a small square object, we'll use Type-C as the input and output, but we need to leave a power port to retain the portable WiFi's "powered connectivity" feature. [Approximate circuit diagram below]

The PCB slot is for heat dissipation
of the portable WiFi. After removing the portable WiFi, there's no antenna (the antenna on my model is integrated with the casing), so a PCB antenna is needed, which can be used to cover the docking station.

When soldering the portable WiFi antenna, be careful to find the actual antenna contacts!!!
Because I wasn't careful during my first soldering attempt, the receiving antenna wasn't soldered properly, resulting in a weak signal. I only discovered the problem after a week of use and upon inspection.

II. Dock (SL2.2S) [7.4cm * 3.5cm] (Anti-static version)
Since I'm home and can connect to my home Wi-Fi, the portable Wi-Fi adapter is no longer needed. However, adhering to the principle of "the smaller the non-essential, the better," I made a pure docking station (anti-static version). I used the SL2.2S chip because it's slightly better than the SL2.1A.
Based on my experience making a portable Wi-Fi docking station before, and considering this docking station is a gift, I added a transient voltage suppressor diode to prevent static electricity (it needs to be durable since it's a gift). I also added a 100nF filter capacitor to the power supply of each USB port (optional), but I strongly recommend soldering the 10uF one!!!
