WT32-ETH01 is an embedded serial to Ethernet module based on the ESP32 series WT32-S1 MCU. The module integrates an optimized TCP/IP protocol stack, which is convenient for users to easily complete the networking functions of embedded devices while reducing development time costs. In addition, the module is compatible with half-pad and through-hole connectors. The board width is a universal width and therefore, it can be directly soldered to boards, connectors, or even breadboards, which is convenient for users to use in different scenarios.
The ESP32 series of ICs are SOCs that integrate 2.4GHz Wi-Fi and Bluetooth dual-mode, with ultra-high radio frequency performance, stability, versatility, reliability, and ultra-low power consumption.
Highlighted Features
- Support complete TCP/IP protocol stack
- Rich wireless communication interface
- Multiple working modes using through holes and half-pads
