Ring terminals connect two or more wires to a single connection point, by fitting the open face of the terminal over a stud. They create a solid connection as the ring that is fitted over the stud cannot come loose or fall off. This removes the possibility of the ring terminal disconnecting. They are widely known for the semi-permanent connections that they create. To make ring terminals even better, they can easily be used with two or more wires depending on the application. Ring terminals are the most secure type of tongue style terminal available and are commonly chosen for their durability, ease of use, and longevity in tough conditions.

If you done using a breadboard for Pico and are ready to take your prototype to solder, you will love this board.
It can be tricky to work out which pin is which when using a Raspberry Pi Pico
with prototyping board. The MonkMakes Pico Proto PCB solves this problem by
labeling the Pico pins on the PCB.
The MonkMakes Pico Proto PCB makes it easy to make soldered prototypes using the Raspberry Pi Pico. You can solder the Pico to the prototyping board using the castelations around the edge of the board, or using header pins, or even solder header sockets onto the Pico Proto PCB so that you can easily swap out the Pico.

The Spy Camera for Raspberry Pi is smaller than a thumbnail with a high enough resolution to see people, or ghosts, or whatever it is you're looking for. It's about the size of a cell phone camera - the module being just 8.5mm x 11.3mm - and has a stick-on back so it's easy to mount in a doorbell or behind a teddy bear's eye (might as well be creative!)
The camera comes with a 289mm (11.4") long cable so you can extend and mount your Pi away from the camera. Like the Raspberry Pi Camera Board, it attaches to your Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data.
The camera is connected to the BCM2835 processor on the Pi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi.
The sensor itself has a native resolution of 5 megapixel, and has a fixed focus lens onboard. In terms of still images, the camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30, 720p60 and 640x480p60/90 video.
