ESP32 WT32-EHT01 module - WiFi Bluetooth RJ45 compatible with Arduino Tasmota HA

The WT32-ETH01 module is an advanced component based on the ESP32 series, specialising in serial-ethernet connectivity. Using the Espressif MCU WT32-S1 microcontroller, this module integrates LAN functionality with existing Wi-Fi, Bluetooth, UART, and Ethernet capabilities. It has the advantage of an embedded, optimised TCP/IP protocol stack that simplifies the implementation of network functions in embedded devices. The module supports four modes of operation: TCP server, TCP client, UDP server, and UDP client, which significantly increases its versatility. ESP32 chips stand out for their high RF performance, stability, versatility and low power consumption, combining 2.4GHz Wi-Fi and Bluetooth in dual-mode. The WT32-ETH01 is ideal for both industrial and home IoT applications, working well with HomeAssistant and Tasmota platforms. Important: The module does not have a USB connector. A USB-UART converter compatible with a logic voltage of 3.3V will be required for its programming.
