51 microcontroller one-click automatic download without power failure and restart

Overview

Supported functions include:
8-digit LED display, 4-digit digital tube, 4 buttons, serial communication, buzzer, LCD1602/LCD12864, OLED, EEPROM, infrared, and DS18B20/DHT11.
Except for the socket, all components use surface-mount materials, and the resistors and capacitors are in 0603 packages (preferably packaged in a modular fashion). The attached file contains simple LED test code (there's plenty of open-source code online, so I won't elaborate).

lie?
We have watched "True Lies" and sometimes we also make up "white lies". Remember that "using lies to verify lies will definitely result in lies."
