Description:
Interface Introduction
1. Main control MCU: STM32F103C6T6;
2. Network chip: W5500 full hardware TCP/IP protocol stack Ethernet chip;
3. Network interface: 10M/100Mbps HR911105A network transformer:
4. 5.08mm terminal power supply port: DC7-28V power input, in which GND is negative;
5. MCU reset button: short press to reset;
6. MCU SWD debugging interface: used for secondary development and programming;
7. MCU UART debugging interface: GND, RXD, TXD: TTL level UART communication interface, GND, RXD, TXD are connected to GND, TXD, RXD of the external control terminal respectively. It supports connecting to 3.3V/5V external TTL serial port and is used for serial port by default. Check the device IP address and port number, the baud rate is 115200;
8. 1-way relay switch signal output: NC: Normally closed end, short-circuited to COM before the relay pulls in, and floating after pulling in; COM: Common end; NO: Normally open, floating in the air before the relay pulls in, and connected to COM after pulling in Short.
