This set of 5 Male IC headers with 40 pins is a convenient and flexible choice for your electronic projects. The pins have a spacing of 2.54 mm between them, and the header can be broken down pin by pin. This allows you to divide the header into smaller groups, depending on your project needs. An important detail to consider is that these headers, due to their round holes, are not compatible with standard male/female headers. However, this makes these headers more compact than the standard versions.
