Project with Raspberry Pi 1B
We have a Raspberry Pi 1B from June 2012 with only the 26 pin on the GPIO header. On it a 480x320 3.5" display is mounted that needs a special driver. More on that in the Software section. It has only 2 USB2.0 ports. One for mouse/keyboard combo, the second for the TP-Link TL-WN725N WiFi dongle.
Download the recent Raspberry Pi OS and install it on a SD card. I assume it is Raspbian Buster.
The WiFi dongle TP-Link TL-WN725N has the Realtek 8188eu chip on it that has only some old drivers in the repository that don't work. Following the recommendations from MrEngman you should edit the wpa_compliant file with
me@rpi:~/ $ sudo nano /etc/wpa_supplicant/wpa_supplicant.confand enter
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB
network={
ssid="Your-Network-Name"
psk="Your-Network-Password"
}
Check your kernel version with uname -a. Find and download the respective driver from the fars-robotics.net website. Then unpack and install the driver:
me@rpi:~/ $ tar xf 8188eu-your-kernel-version.tar.gz
me@rpi:~/ $ sudo ./install.shAfter reboot it should work.
For the display you need this driver:

Download Raspbian OS from scratch. The regular graphical screen would not start, performed some tests on the browser. For example, the octane benchmark performed only 155 points.

Initiated in March 2020, this robot car is powered by a Raspberry Pi 1B with 3.5 inch 480x320 display for 80x25 characters at the terminal. It needs 40 seconds to boot. Reactivated in November 2020.
