NodeMCU ESP32-S 4MB WROOM 38 pins (OT2112-C52)

This NodeMCU ESP32-S is similar in performance and features to the ESP32 Devkit V1 but has 38 pins instead of 30. This provides more connection options.
In addition, this ESP32-S fits on a standard breadboard.
ESP32 voltage VIN or USB: The power for the ESP32-S is supplied via the built-in Micro USB connector (5V) or directly via the "VIN" pin. The ESP32-S can operate on an external power supply of 6 to 20 volts. If you use more than 12V, the voltage regulator can become very hot and will shorten its lifespan. In that case, it is better to use a STEP DOWN converter to bring the voltage down.
