Raspberry Pi Region Settings
Sorry to hear you received UK specific Raspberry Pi's.
No worries though, we can still make use of them for your internship.
Wifi Settings
One change you'll need to make if you're using WiFi to connect your Pi to the internet, is to set the correct region for the WiFi antenna.
To do this, enter
sudo raspi-config
to enter the menu-driven program. Use the arrow keys and enter to navigate to
Localisation Options --> Change Wi-fi Country --> US United States --> OK --> Finish.
Regarding Keyboard Layout
If your keyboard has the physical labels for the UK specific keys like £ instead of $, then we would recommend not changing the keyboard layout, as having a different layout than what you actually see might be confusing.
