ESP32-STICK

Description

ESP32-Stick is a versatile open-source development board based on the ESP32-WROOM chip, designed for reliable and stable projects requiring Ethernet connectivity and Power over Ethernet (PoE) support. It’s ideal for smart home, automation, and IoT applications.

This board was created as part of a successful Kickstarter campaign and is available in three versions:

• ESP32-Stick – base model without PoE

• ESP32-Stick-POE-P – supports passive PoE (9–57 V)

• ESP32-Stick-POE-A – supports active PoE (44–57 V)

Key Features:

• ESP32-WROOM microcontroller (WiFi + Bluetooth)

• 17 available GPIO pins (Ethernet uses separate pins)

• USB-C connector for power and programming

• CH340G USB-UART converter (no external programmer needed)

• LAN8720A Ethernet chip

• USER LED (GPIO2), reset and user button (GPIO0)

• Flash memory: 16 MB

• All versions share the same size, pinout, and CPU – easy to swap

• Compatible with Arduino IDE, PlatformIO, ESPHome, ESPEasy

• Pin headers included (unsoldered)

Power Options:

• USB-C (5V)

• External input: 3.3V or 5V

• ESP32-Stick-POE-P: Passive PoE 9–57 V (with Si3404 chip, 5V/2A output)

• ESP32-Stick-POE-A: Active PoE 44–57 V (with Si3404-A chip, 5V output)

Highlights:

• Reliable Ethernet connectivity (more stable than WiFi for many use cases)

• Plug-and-play programming with built-in USB-UART

• Power via Ethernet (PoE) – no need for extra power adapters

• Fully software-compatible across all board versions

• Great for wired projects or industrial setups
