NS4-V2-TB 4-port serial to Ethernet module development board dedicated test kit with USB-to-TTL
[Interface signal]：Ethernet
[Number of serial ports]：4
[Operating voltage]： DC 3.0-5.5V
[Size]：89*49mm
[Product weight]：32.3±1g
[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.
