[Interface signal]:Ethernet
[Interface mode]:UART serial port
[Size]: 27*27*2.8mm
[Working voltage]:3.0~5.5V
[Introduction]:The NS8-TB test kit comes with a USB-to-TTL circuit without the need for users to connect an external converter, and leads to reset and factory reset pins for external buttons for easy operation, and also connects the operating status indicator pins to external LEDs for users to observe the status.
