If you ordered the circuit board with the assembly service, the small components are already soldered. Otherwise the LDO and the 0805 and 0603 have to be soldered manualy. The 0603 components are quite small, but can still be easily soldered. Just tin a pad on one side, heat the tinned pad with the soldering iron and push the component into the molten solder with tweezers. Then solder the other side. If necessary, solder the first pad again.

Proceed in the same way to solder the ESP32 module. Tin one single pad first. Put on the ESP32 module and melt the tinned pad. If the ESP32 module is aligned straight, the remaining contacts can be soldered. With some flux (I use a paste) the contacts can be easily soldered without bridges.

The THT button (BOOT), the SMD button (EN) and the two 3mm LEDs shouldn't cause any problems. Start with the SMD button. Same procedure as before.

The legs of the LEDs can be bent by 90° quite close to the housing. Observe polarity! The long leg goes in the hole with the + mark. Make sure the button and LEDs are soldered straight and flat to the board so the front panel will fit properly.

Finally you should solder the GND area of the ESP32 on the backside. Use a little more heat and time and flood the holes with solder.

If everything went well and you cleaned the circuit board, it should look like the following image.
