Features
-
Supports most 30-pin ESP32 and ESP8266 modules.
-
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).
-
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
Universal 30 or 38-pin ESP32 Compatibility – Supports most 38-pin ESP32 modules with 0.9″, 1.0″, and 1.1″ spacing. Dual 2×19-pin headers ensure secure connection across different board designs.
