Amazon. 3V, 12V to 5V, 24V to 3. The Mega itself will be powered with either 9V from a PSU or with 5V if the USB is in use. Order Now! Isolators ship same day. The opto you have is characterized at both 5 mA vF and 20 mA vF. Supports 12V to 3. A Optocoupler also called a photocoupler, optical isolator or opto-isolator is a small chip that transfers signals between two isolated circuits using light. Unless you need fast response, running the LED in the opto at 5 mA shouldn't hurt anything. ANAVI Opto-isolator Open source hardware printed circuit board for Arduino, ESP32, ESP8266, Raspberry Pi, etc. , with high quality and high Learn how to use the 1 Channel Way Optocoupler Isolation Module PC817 EL817 12V with detailed documentation, including pinouts, usage guides, and example projects. 3V, 24V to 5V. Each input can be configured for 5V, 12V, or 24V input using a jumper. I'm keen to keep the Mega and the 12V supply completely isolated from each other rather than using a voltage DONGKER has a variety of modules, including PWM Driver Module, Optocoupler Isolation Board, Temperature Humidity Sensor Module, Voltage to Current Module, etc. Relé de 2 a 8 maneiras Relé vem com o isolador Opto Pinout de recorte: Dc+ = entrada de tensão DC, tensão de entrada do módulo de 5V é de 5V, o módulo de 12V é de 12V.
