Ebyte NS1-TB USB/TTL to RJ45 Ethernet Evaluation Board

Ebyte NS1-TB USB/TTL to RJ45 Ethernet Evaluation Board

NS1-TB is a serial server that realizes serial data ⇌ Ethernet data conversion. It has a variety of Modbus gateway modes and MQTT/HTTP IoT gateway modes, which can meet the networking functions of various serial devices.

The NS1-TB test kit is equipped with a USB to TTL circuit, which does not require the user to connect the external converter, and the reset and restart pins are connected with external keys for easy operation. At the same time, the operation status indicator pins are connected with external LEDs for the user to observe the status.
