The Thai dual socket is specified in figure 4 of TIS 166-2549 and is designed to accept Thai plugs, and also Type A, B, and C plugs. Chinese dual sockets have both an unearthed socket complying with figure 5 of GB 1002-2008 (both flat pin and 4.8 mm round pin), and an earthed socket complying with figure 4 of GB 1002-2008.
The important socket dimensions which the standard does specify are: A minimum insertion of 9.6 mm from the face of the socket-outlet to the first point of contact with a live part, [67] a minimum distance of 9.5 mm from the line and neutral apertures to the periphery of the socket face, [68] and not to exceed dimensions for the apertures of 7. ...
Example of a Europlug. The Europlug is a flat, non-rewirable two-pole, round-pin domestic AC power plug, rated for voltages up to 250 V and currents up to 2.5 A. [1] It is a compromise design intended to connect low-power Class II appliances safely to the many different forms of round-pin domestic power socket used across Europe.
The addition is a 3 ⁄ 16-inch (4.8 mm) diameter round or U-shaped ground pin, 1 ⁄ 8 in (3.2 mm) longer than the power blades (so the device is grounded before the power is connected) and located from them by 1 ⁄ 4 in (6.4 mm) edge-to-edge or 15 ⁄ 32 in (11.9 mm) center-to-center.
In early 1802-based microcomputers, the companion graphics Video Display Controller chip, RCA CDP1861 (for the NTSC video format, CDP1864 variant for PAL), used the built-in DMA controller to display black and white bitmapped graphics on standard TV screens at up to 64 pixels horizontally by 128 pixels vertically. The 1861 was also known as the ...
The 1280 × 1024 resolution is not the standard 4:3 aspect ratio, instead it is a 5:4 aspect ratio (1.25:1 instead of 1. 3:1). A standard 4:3 monitor using this resolution will have rectangular rather than square pixels, meaning that unless the software compensates for this the picture will be distorted, causing circles to appear elliptical.
The nano-SIM measures 12.3 mm × 8.8 mm × 0.67 mm (0.484 in × 0.346 in × 0.026 in) and reduces the previous format to the contact area while maintaining the existing contact arrangements. [30] A small rim of isolating material is left around the contact area to avoid short circuits with the socket.
Raspberry Pi 5 supports booting from NVMe SSDs attached directly to the PCIe bus with an appropriate adapter or HAT. For video output, HDMI is supported on all versions, and composite video is supported on Raspberry Pi 4 and earlier, with a standard 3.5 mm tip-ring-sleeve jack carrying mono audio together with composite video.
