A 7-port USB hub design based on FE2.1 (verified)

Overview

To address the issue of insufficient USB ports, a 7-port USB hub based on the FE2.1 chip was designed. It uses a Type-C input port to connect to the computer, while the other seven are standard USB 2.0 ports.
This is the second version, adding independent power supply to the first. After prototyping the first version, it was found that it couldn't power devices with slightly higher power; at most, two USB ports would stop working. Therefore, a TPS5450 was used with a 12V adapter for power, with a maximum output of 5V/5A. This effectively avoids the problem of devices not being able to run.
This version has been verified to be working correctly and can be safely replicated.

ESP32 HUB75E Controller

The HUB75 LED panel controller, designed using an ESP32 module, integrates a DS3231 clock chip, DHT11, TF card, and photoresistor detection.

This document
describes the design of the ESP32-S3 HUB75E controller
, a HUB75 LED panel controller designed using the ESP32 module.
It features 8MB of PSRAM for a richer interface, an integrated DS3231 clock chip, DHT11, TF card, and photoresistor detection. Notes: The HUB75E uses a 2.54-16P dual-row female connector, which needs to be soldered to the back.
