Simple Thermometer Based on STC8

 
This project uses the STC8H8K64U, which has ample Flash memory and sufficient expansion space.
Temperature measurement is achieved using a DHT11 sensor.
The screen uses a common four-wire OLED module, which can be easily installed by soldering a socket.
Two LED slots are reserved for future code additions to illuminate the LEDs and impress the user.

Anecdote:
Regarding the LDO emitting light (smoke) on my first power-on (not really),
after checking, I found that some idiot (yes, it was me) had placed the VCC silkscreen on the GND pad, which made me furious (already corrected).
As a result, an LDO and an MCU burned out, thankfully the DHT11 didn't (doge).
 
Regarding the casing:
First time designing a casing, a disaster.
