[Introduction]：The NS4-V2-TB Ethernet module test kit includes a built-in USB-to-TTL converter (only one channel is built-in, switchable via a jumper), enabling quick debugging without an external converter. The reset and factory reset pins are exposed for external buttons, and all module function pins are exposed for convenient external debugging.
