Here’s the short version:

The ESP-01 module put Wi-Fi into the hands of hobbyists. Before the ESP8266 NodeMCU or ESP32, there was this tiny 8-pin board. If you’re working with one today, here’s what you need from its datasheet. esp 01 datasheet

The ESP-01 is limited (only 2 usable GPIOs, 3.3V logic, current spikes), but it’s perfect for simple IoT switches, sensors, or controlling a relay. Always use a level shifter or voltage divider if connecting to 5V logic.
