The WAVE-20655 is a small module that allows for two-channel Ethernet to UART TTL communication. it's bidirectional and also comes with features such as four operating modes, low power consumption, KEEPALIVE support, etc.
The 2-CH UART TO ETH provides an easy way to communicate between UART TTL and RJ45 Ethernet, allowing bi-directional transparent data transmission. 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.
Features
