Description ETH01- is an upgraded version of ETH01, which has the following advantages: 1. ETH01- is upgrading its application AT firmware to AT version 2.4.2.0 2.ETH01- supports POE ingress for Ethernet connections and provides a reserved POE slot for application scenarios. 3.ETH01- communicates with the controller through the SPI bus and converts the data into RJ45 signals for output via the SPI interface. On the other hand, WT32 ETH01 communicates with the controller through a PHY (Ethernet physical layer) transceiver and converts the data into RJ45 signals for output using the PHY transceiver. Features 1.Highly integrated ESP32-C3 module with low power consumption 2.Wireless connectivity with Wi-Fi and BLE and Ethernet 3.Supports AT instructions 4.Supports a complete TCP/IP protocol stack 5.Reserved POE location Description ETH01- is a three-in-one Internet of Things communication gateway based on the ESP32-C3 chip, supporting WIFI, Bluetooth, and Ethernet. It supports a complete TCP/IP protocol stack and AT commands, making it easy for users to achieve network connectivity for embedded devices and significantly reducing development time and cost. The module is compatible with both surface mount and through-hole connector , allowing it to be soldered directly onto PCBs or used on breadboards. Additionally, it has a reserved POE position, making it suitable for scenarios. Due to different product batches, the appearance may be different, but it does not affect use.
