Ethernet To TTL RS232 Serial Converter – RJ45 To TTL Module, TCP/IP Transmission
About this item
This little module is an Ethernet to TTL serial converter—basically, it lets you connect TTL-level serial devices to a network.
It takes data from an RJ45 Ethernet port and converts it to TTL RS232, or the other way around.
It's a TCP/IP transmission module, so you can use it to network-enable old serial devices, microcontrollers, or whatever else speaks TTL.
It's brand new, unbranded, and made in China.
The model is just listed as Ethernet Serial TTL RJ45 Converter.
It's a bare board, so you'll need to know how to wire it up and configure it.
If you're into electronics, IoT, or industrial control, this is a handy tool for getting serial gear on your network.
It's not for beginners, but if you know your way around TTL and TCP/IP, it's a cheap way to bridge the gap.
