| Pin | Name | Description | | :--- | :--- | :--- | | 1 | VCC | 3.3V power input | | 2 | GND | Ground | | 3 | TXD | Serial transmit (connect to MCU’s RX) | | 4 | RXD | Serial receive (connect to MCU’s TX) | | 5 | RST / Link | Optional reset or link status | Operating Temp: -40°C to 85°C (-40°F to 185°F)

The outlines four primary working modes. Choosing the wrong mode is the #1 cause of communication failure.

| Problem | Likely Solution | | :--- | :--- | | Cannot ping module | Check power, Ethernet cable, and that PC and module are on same subnet (or use DHCP). | | Serial data not received | Verify baud rate, parity, stop bits match between module and MCU. | | TCP connection refused | Ensure module is in TCP Server mode, or target server IP/port is correct in Client mode. | | Forgot IP address | Use USR-M0 utility (or USR-VCOM ) to search network for the device by MAC. |
