Features
Stable ESP32 Module: The onboard ESP32-WROOM-32E module with large capacity 4M Byte Flash, supports the use of development tools and provide reference programs in the development environment.
For Development: The I/O ports and UART program download ports of the ESP32 module are all exported, making it convenient for secondary development.
Better Design: On board ESP32 module programmable buttons and reset buttons, on board 1 programmable LED and relay indicator light.
Applicable Scene: On board 8 circuit 5V relay, output switch, suitable for controlling loads with working voltage within AC 250V and DC 30V.
Reliable in Use: The ESP32 8 channel relay development board is equipped with the ESP32-WROOM-32E WiFi and BLE module, and all I/O ports are led out, supporting DC 5-30V power supply. Suitable for ESP32 secondary development learning, smart home wireless control, and other occasion.

Big fan of this all-in-one package. Flashed ESPHome easily and added to Home Assistant.The traces for the relay-switched terminals are run on both sides of the board, so I expect the PCB can handle the full rated current of 10A without excessive heating.Quality wise, everything looks well assembled and all the relays/status LEDs work as expected.One thing to note, the relays consume ~80mA each. When all of them are on + the ESP32, the whole circuit uses ~680mA @ 5V. It was a bit higher than I expected, something to consider for your designs.

I originally was skeptical. I even clicked the "click for refund" button, got a packing slip, packed it up. Then I started doing more reading on ESP32 setup and figured it out, took it out of the package and tried it out. In my case I set it up to work with Home Assistant. You need a USB to TTL converter, and some jumper wires to program it - which is easy. You have to solder the pins on this unit, which they have in the package. The ESP32 pins are not labeled 1 through 8 but start at 12, then 13 - (you can see them on the back of the uniti). This seems to work better than triggering relays with the Raspberry GPIO pins.

A little more planning would have gone a long way. The pins used for the relays jitter when WIFI is turned on. If you don’t need wireless communications, then it’s fine.
