12V Power Supply Circuits - ElectroSchematics
Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. 12V dc power supply schematics

Transistor Relay Driver Circuit with Formula and Calculations
Sep 14, 2022Hi Swagatam, I have a query please. I am planning to use 433MHz Tx Rx pair ( single channel) to energise a 12v relay, which will require a relay driver as in your example above. For the simple BC557 circuit I have calculated the theoretical resistor value as 41K so I would expect to use 47K.
ESP32 Relay Module – Control AC Appliances (Web Server)
Dec 18, 2019It can be controlled with low voltages, like the 3 provided by the ESP32 GPIOs and allows us to control high voltages like 12V, 24V or mains voltage (230V in Europe and 120V in the US). 1, 2, 4, 8, 16 Channels Relay Modules. There are different relay modules with a different number of channels.
