It is easy to use, along with features like fast data rate, low power consumption, high stability, suits applications such as safety & security, IoT, and so on. Specifications 140mA Operating current. TCP/UDP Operating mode 300bps ~ 921.6Kbps UART baudrate UART TTL level:compatible 3.3V / 5V Storage temperature:-55℃ ~ 125℃ Operating temperature:-40℃ ~ 85℃ Dimensions: 53.00 Γ— 22.00mm Control interface:supports host boards including Raspberry Pi/Arduino/STM32... Development Resource: https://www.waveshare.com/wiki/2-CH_UART_TO_ETH Package Content 2-CH UART TO ETH x1 Review: This seems like it's a nice enough adapter. I was able to get it configured with my computer, but it didn't send the information correctly to my UDP device, so it never worked correctly. I think this must only work well with Arduino or a Raspberry pi, or to use as a test board. ## Features - 2-CH UART to Ethernet Converter, serial port transparent transmission module.
