The same as installing any other Operating System for an RPi board.
What is the reason for wanting an obsoleted Operating System, and what do you think is the impediment to installing it?

and this need to Raspbian Jessie OS. I can use another OS for this project?
really ? are you sure ?pcmanbob wrote: ↑Wed Jul 01, 2020 9:45 amIf you are going to build that project please don't follow the connection diagram for the ultrasonic sensor , powering it with 5V as required will result in the echo also being at 5V, this will damage you pi gpio over time finally resulting in the failing pi.
you need to add a potential divider circuit to the echo output, like this
and I would not power the motors from the 5V pin of the gpio header.
https://www.raspberrypi.org/documentati ... /README.mdEach of the three banks has its own VDD input pin. On Raspberry Pi, all GPIO banks are supplied from 3.3V. Connection of a GPIO to a voltage higher than 3.3V will likely destroy the GPIO block within the SoC.
thank youpcmanbob wrote: ↑Wed Jul 01, 2020 10:18 amYes I am sure,
all raspberry pi's have a 3.3V gpio, applying 5V to a gpio pin will cause latch-up of that pin and damage to the chip, which will spread over time resulting in pi failure.
You will find many warnings on many posts on this forum saying pi gpio is not 5V tolerant.
and from the official doc's
