Hello

Videos/tutorials in this channel are a great learning tool, easy to understand.

 

Is an IRF520N module suitable for up-volt a serial 9600 tx signal?

(up volt to 12Volts, required for Arduino automotive scanning tool project)

 

If not any better options?

Hi @fedehe,

   Sorry, I am not clear which particular circuit/project you are referring to ... perhaps it would help if you started a new project thread and provided an explicit reference to what you like to achieve.

----------

It is not clear if you are referring to the 'traditional' RS232 communication standard, which uses voltages of about 3V to 25V and -3V to -25V to represent the logical states 0 and 1. Conversion from an Arduino serial tx (and rx) pin  to RS232 voltages is most easily done using a specialised device.

For an example and further information of such a converter, see https://www.sparkfun.com/products/449 , including the document links on the page.

Best wishes, Dave

@davee Thanks for your reply I will check the link and specific hardware solutions.

Project works with Uno's standard tx & rx pins sending exadecimal bytes. Tx doing great oscilloscope already but 5V.
Code not mine, downloaded from the internet.
