Powerline Communications (PLC) Demo Board

- The JARViE PLM Demo Board offers users a simple and low-cost entry point into learning about power-line communications. Couple this modem with a microcontroller to bidirectionally communicate with other devices or systems over AC or DC power lines. Applications include lighting control, home appliance control, energy/heating control and up to 3,000 feet data transmission home power networks.
How it works:
Each demo board has an NXP TDA5051a powerline modem IC. This modem takes in a digital message from an MCUs UART bus, an Arduino UNO in this example, and translates this digital message into an equivalent analog message. Additional circuitry on the demo board sends the analog message over the 120/240VAC of your home, if the demo board is connected to a home outlet. Ideally, the analog message will be broadcasted across all the 120/240VAC wires of your home (to all home outlets), so another demo board connected to another home outlet will hear this message. The demo board has special filtering to only receive messages sent by other powerline modem demo boards and reject all other noise or communications between non-demo board devices. Once a demo board receives an analog message sent over the home power lines, it converts it to an equivalent digital message and sends it to an MCU over its UART bus. Additionally, the demo boards can communicate over DC powerlines as well.

Nice work. Powerline communication has been seriously overlooked in home automation. I'm not sure why X10 stopped evolving and we skipped straight to over-complex wireless systems. A lightbulb doesn't need wireless technology, it's already got wires!
That's very cool, I've been thinking of a project with PLC, looks like a nice board
Thanks sir, leaned alot.
Sir, Thanks, learned a lot :).
Nice :)
Hi buddy can you please tell me whih device you have use here for interfacing AC lines with microcontroller
Do they need any adjustment to operate over 24V AC? Or will they work directly, without altering any component values?
On screw terminal 3, what does N/C mean? Normally Closed, lol, or Not Connected?
Hi sir,I can't understand how the communication take place between master side and transmitter side. because there is no connection between the two power line modules. then how transfer data between one side to another. please clarify my doubt .please help me
un gusto, consulta cuanto demora el envio a chile???? saludos
