Raspberry Pi 3 Serial Console Connection

In this segment of the tutorial you will need to have your usb serial adapter plugged into the rs232 adapter.

Raspberry pi 3 serial console connection. You can connect the raspberry pi to a pc using a usb serial cable or if it has an rs 232 port a level converter circuit see above for. The default rate of the raspberry pi boot loader is 115200 baud. Connect the serial to usb converter to the raspberry pi board as is shown in the circuit. The raspberry pi 3 has changed things a bit and you might need to add the option enable uart 1 at the end of boot config txt see this post by a pi engineer connection to a pc.

The raspberry pi 3 model b b 4 and raspberry pi zero w contain two uart controllers which can be used for serial communication the mini uart and pl011 uart. Then plug the raspberry pi supply and connect the converter to your pc. Raspberry pi 3 and raspberry pi zero w ttys0 enabled. Picocom q baud 115200 dev ttyusb0 after powering the raspberry pi with an opensuse sd card image you should see the boot loader output inside the terminal.

This will be slightly different depending on whether you are running a raspberry pi 3 or not.
