Ebyte NE2-S1-TB USB/TTL to RJ45 Ethernet Evaluation Board

Ebyte NE2-S1-TB USB/TTL to RJ45 Ethernet Evaluation Board

NE2-S1-TB single serial port server module is a serial port to Ethernet module that realizes bidirectional transparent transmission of serial port and Ethernet data. Users do not need to care about the specific details, and the protocol conversion is completed inside the device. It has a variety of Modbus gateway modes and MQTTC/HTTPC IoT gateway modes, which can meet the networking functions of various serial devices/PLCs; it adopts industrial-grade design standards to ensure equipment reliability. This Ethernet module uses a 1.27mm stamp hole interface and is compact in size, making it easy for users to integrate into the system.

The NE2-S1-TB test kit comes with a USB to TTL circuit , eliminating the need for users to use an external converter. It also provides reset and restart pins for external buttons for easy operation , and also connects the operation status indicator pins to external LEDs for users to observe  the status.
