The Vacus ESP32-LAN8720 PoE module is a compact, productionready board combining an Espressif ESP32-WROOM-32E wireless microcontroller with 10/100Base-T Ethernet (SMSC LAN8720A) and IEEE 802.3af-compatible Power-over-Ethernet input. The on-board AG9905M PoE converter delivers a regulated 5V/9W supply directly from the Ethernet cable, eliminating the need for a separate power supply. An LM1117 LDO provides a clean 3.3V rail for the ESP32 and peripherals. A CP2102-GMR USB-to-serial bridge with auto-boot circuitry enables plug-and-play firmware flashing via USB Micro-B. Expansion headers expose additional ESP32 GPIOs, and a JST connector provides power and serial I/O for host system integration.


Features:

  1. ESP32-WROOM-32E Wi-Fi + Bluetooth MCU
  2. 10/100 Ethernet via LAN8720A controller
  3. IEEE 802.3af PoE support (single cable power + data)
  4. AG9905M PoE converter (5V, up to 9W output)
  5. Onboard LM1117 3.3V voltage regulator
  6. CP2102 USB-to-serial with auto-boot
  7. JST connector for power and UART interface
  8. Expansion headers for GPIO access

Package Includes:

1 x VACUS ESP32-LAN8720 PoE-R1 Module

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
