Headers can be either straight (vertical) or right-angle, the latter form is sometimes used to connect two PCBs together horizontally. Most often, headers are available in one or two rows, though three or more rows are available from some manufacturers. They are often sold as long strips (typically

For multi-row pin headers, the pin number is more complex, because knowing the location of pin 1 doesn't automatically ensure how the remaining pins are numbered. Typically for headers attached to ribbon cables, the pins are numbered so they go linearly across the cable. Because of the way the

In absence of a pin 1 designation on the header, if a designation is missing from the header, the PCB may have a marking indicating orientation (historically, the solder pad around the hole of pin 1 of a THD header is often square rather than round).
