NS1 Serial to Ethernet Module

[Protocol]:IPv4、TCP/UDP、HTTP、MQTT

[Interface]:TTL(3.3V)、Ethernet port (RJ45)

[Size]:17 x 19 x 4mm(length x width x height)

[Weight]:1.6g ± 1g

[Introduction]:NS1 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.

Pin Definition
No. Pins Function Instruction
1 GND GND Common ground terminal, power supply negative terminal input;
2 PA14 RX_LED The serial port receives the indicator light output, the default output is high level, when there is data input, it outputs low level, and when there is continuous data, it outputs a square wave signal with a period of 80ms and a low level of 20ms;
3 PA13 NC Default dangling;
4 PA12 NC Default dangling;
5 RXD1 NC Default dangling;
6 TXD1 NC Default dangling;
7 PB9 LINKLED After the network cable is inserted, it outputs a low level, and the network cable is not connected to output a high level;
8 PB8 SPDLED SPD indicator;
9 TCK NC Default dangling;
10 TIO NC Default dangling;
11 3.3V 3.3V output Can output 3.3V, please do not connect large load
12 GND GND Common ground terminal, power supply negative terminal input;
13 RX_P RX_P Ethernet receives RX+ signal;
14 RX_N RX_N Ethernet receives RX-signal;
15 TX_P TX_P Ethernet sends TX+ signal;
16 TX_N TX_N Ethernet sends TX-signal;
17 D+ NC Default dangling;
18 D- NC Default dangling;
19 TXD0 TXD0 The serial port sends data, the TTL level communication voltage only supports 3.3V, if it is connected to 5V, it needs level conversion;
20 PB6 RTS MODEM output signal of serial data, request to send;
21 PB5 NC Default dangling;
22 RXD0 RXD0 The serial port receives data, the TTL level communication voltage only supports 3.3V, if it is connected to 5V, it needs level conversion;
23 PB3 485_EN RS485 software enable control pin, when the serial port sends data, it is high-level output, and the default is low-level output;
24 PB2 NC Default dangling;
25 PB1 NC Default dangling;
26 PB0 CTS MODEM input signal of serial data, clear to send;
27 RST nRST External reset input, active low;
28 PB22 NC Default dangling;
29 PB21 LED2 The network port link indicator output, the default output high level, the output low level after the connection is successful under the TCP protocol, and the default output low level under the UDP protocol;
30 PB20 LED1 Running indicator, after the module is powered on and initialized, this pin outputs a 5Hz square wave;
31 ANT NC Default dangling;
32 PA4 IO_RST To restore the factory pins, an external reset button is required, and the low level is valid for about 5s;
33 PA5 NC Default dangling;
34 PA15 TX_LED The serial port sends indicator light output, the default output is high level, when there is data output, it outputs low level, and when there is continuous data, it outputs a square wave signal with a period of 80ms and a low level of 20ms;
35 GND GND Common ground terminal, power supply negative terminal input;
36 VCC VCC Positive power input, support 3-5.5V input;
