Preventing Damage to ESP-01S
To avoid potential damage to your ESP-01S module, it's crucial to exercise caution when dealing with GPIO0. To enter flash mode, GPIO0 must be connected to GND. If your code is configured to drive GPIO0 with a logic HIGH signal and you inadvertently ground it, you run the risk of creating a short circuit. This can lead to a high probability of damaging the ESP8266 chip, making it vital to be attentive and mindful of your GPIO0 configurations to maintain the integrity of your module.
