Before You Connect

Check the pinout and power-input requirements for this specific V1.1 board before wiring your project. The ESP32 module’s supply-voltage specification should not be confused with the development board’s USB or external power-input requirements. Power consumption varies with firmware, connected peripherals and wireless activity.
