Learning objectives

  • Identify this example, its board class and pin limitations.

Before this introduction

ESP is a family, not one pinout. ESP32-DevKitC V4 with an ESP32-WROOM-32E module is a named microcontroller example with wireless capabilities. Its GPIO uses 3.3 V logic; USB/5 V power is not permission to send 5 V into GPIO. Some pins have boot, flash or input-only roles. Wireless hardware does not mean network IoT is implemented here.

Learn only: circuit building, board simulation, firmware export and physical connection for this board are not available here.
