Good hardware, sparse docs
The module itself works well and connection is stable. I wish there was more detailed documentation included in the package.

Solid module
Works as expected. Had to adjust some clock settings in my code but the hardware is solid.

Great value for money
Cheaper than other options I found and performs just as well. Shipping was fast too.

Perfect for STM32 Projects
This module integrated seamlessly with my STM32F4 board. The RMII interface is straightforward if you have the right pinout.
Q: What is the logic voltage level?
A: The module operates at 3.3V logic levels. Please ensure your microcontroller is 3.3V compatible.
Q: Can I use this with Arduino Uno?
A: Arduino Uno lacks the necessary RMII interface hardware. This is better suited for STM32 or ESP32.
Q: Does this module support Power over Ethernet?
A: No, this module is for data transmission only and does not support PoE functionality.
Q: Is the RJ45 connector shielded?
A: Yes, the RJ45 jack includes shielding to help reduce electromagnetic interference.
Q: Is this compatible with ESP32?
A: Yes, it is compatible with ESP32 using the RMII interface, though you may need to configure GPIO pins accordingly.
