Great for learning
Used this for a university networking project. It handled TCP/IP stack well. Shipping was fast too.

Good value for money
Solid build quality. The only reason for 4 stars is that the pinout diagram could be clearer, but otherwise it functions perfectly.

Reliable connectivity
Much more stable than WiFi for my IoT sensors. No packet loss observed during testing over 48 hours.

Easy to integrate
Plug and play with my development board. The LED indicators help a lot with debugging network issues.

Works great with ESP32
I used this module to add wired Ethernet to my ESP32 project. The connection is stable and setup was straightforward using standard libraries.
Q: Does it support Gigabit Ethernet?
A: No, the LAN8720 chip supports 10/100 Mbps speeds only.
Q: What library should I use for ESP32?
A: The standard Ethernet library included in the ESP32 Arduino core works well with this module.
Q: Is the RJ45 connector shielded?
A: Yes, the jack includes shielding to reduce electromagnetic interference.
Q: Can I power this via USB?
A: You need a 3.3V power source. Some development boards provide this pin directly.
Q: Is this compatible with 5V Arduino boards?
A: This module operates at 3.3V logic. If using a 5V board, you will need a logic level converter.
