Compatibility Notice — Please Read Before Purchase

This breakout board is compatible with most 30-pin ESP32-WROOM, ESP32-WROVER, and 30-pin ESP8266 NodeMCU development boards ONLY.

1. It is NOT compatible with any boards in the following ESP32 series:• ESP32-P series (e.g. ESP32-P4)
• ESP32-S series (e.g. ESP32-S2, ESP32-S3)
• ESP32-C series (e.g. ESP32-C3, ESP32-C6)
• ESP32-H series (e.g. ESP32-H2)Before purchasing, please verify the following about your development board:1. Chip model — must be ESP32-WROOM, ESP32-WROVER, or ESP8266
2. Pin count — must be exactly 30 pins
3. Pin layout — must match the standard 30-pin WROOM / WROVER or ESP8266 NodeMCU pinout

Compatibility Table

Key Features:

• Supports 30-pin ESP32-WROOM and ESP32-WROVER development boards, and 30-pin ESP8266 NodeMCU boards ONLY

• Includes two sets of 2×15-pin headers for enhanced compatibility with a variety of modules with pin widths of 0.9/1.0/1.1 inches
  (22.86/25.4/27.94 mm).

• Each GPIO port has an LED indicator to display the status (high/low) of the pins, making it easier to debug and verify code without
  additional wiring.

• Independent LED, The status LED is driven by the chip instead of the GPIO so the GPIO will not be affected.

• Features a reverse power protection circuit to prevent damage if the power is connected incorrectly.

• On-board power switch for convenient control.

• Dual power supply: 5V/2A and 3.3V/500mA, providing ample power for servos and sensors.

• Automatic power switching between USB and external power sources.

• External power input via screw terminals or DC jack (7-12V recommended).

Voltage Selection:

• The V_Selector jumper allows you to choose between 3.3V and 5V for the V pin. By default, the V pin is set to 3.3V. Ensure the correct
  voltage is selected to avoid damaging the board or connected devices.

• 2.54mm pitch pin headers and screw terminals for seamless connection to sensors, servos, and other peripherals.

• On-board 3-pin interfaces with V and GND pins for easy sensor or servo connections
