Can I connect 5 V sensors directly to its pins?
No. The ESP8266EX operates at 3.3 V logic, so 5 V signals must be level-shifted before they reach the board's pins. Use 3.3 V sensors or a logic-level converter.
How is the board powered and programmed?
It can be powered over USB or from a 9 V to 12 V supply, with the on-board regulator providing 5 V at up to 1 A. It is programmed through its USB port using the CH340 uploader and can be used with the Arduino IDE after installing the ESP8266 board package.
