To design a temperature and humidity sensor MCU based on Tuya Smart and Lichuang EDA, choose the STC8A8K64S4A12 chip. The subsequent code control needs to be learned. The sensor chooses SHT30-DIS-B, which highlights a high quality and low price, but its size is too small and may be difficult to weld. Some Tuya modules It is still the familiar WBR3, which plays a role in wireless data transmission. OLED has found suitable components with a size of 0.96 and corresponding ports on the Internet. I have never drawn the USB to ttl download circuit before, I hope it will work. Because I am not familiar with the power supply, I still used the AMS1117-3.3V from the last training camp.
