ESP32 DevKit V1 (DOIT 30-pin) Pinout & Specifications

Welcome to the definitive pinout guide for the ESP32 DevKit V1 (DOIT 30-pin).

Dual-core Wi-Fi and Bluetooth microcontroller powerhouse (30-pin version).

Key Specifications

• Operating Voltage: 3.3V
• Input Voltage: 5V via USB or VIN
• Wi-Fi: 802.11 b/g/n
• Clock Speed: 80-240 MHz

Important Wiring Notes

• Power: ESP boards use 3.3V logic. Do not connect 5V sensors directly to the GPIO pins without a logic level shifter!
• Strapping Pins: Be careful using pins like GPIO 0, 2, 5, 12, and 15, as they are used during the boot process to determine the boot mode.
