Network control switch [Copy link]

Hello, seniors. I want to make a control circuit to control the TTL level by sending codes through the network. I checked some information and it seems to be made with a network control switch. I don’t know the internal circuit structure of this network switch. I would like to ask seniors how to make such a network control switch circuit by myself.

Use MCU to implement it. Select the appropriate MCU and interface according to the "network" you need to access, and then make a certain IO of MCU output the TTL level you want according to the protocol. However, from the description of the original poster, the original poster did not clarify the specific application requirements, which is absolutely not possible.

Commonly used wired control "networks" include 485, CAN, MODBUS, LAN, power carrier, etc.; commonly used wireless control "networks" include infrared, UHF, Bluetooth, zigbee, wifi, GPRS, LORA, NBIOT, etc.
