This compact adapter on a PCB base and the ideal solution to connect standard USB devices directly to your computer's motherboard. It allows you to convert a USB 2.0 to 9-pin (mask) header to a standard USB-A port located inside the case. It is particularly useful to install internally components that require a constant USB connection without occupying the external doors of the PC, such as wireless receivers for mouse/keyboards, software license dongles (USB keys), Bluetooth modules or software controlled LED lighting systems. Low-profile design ensures a minimal footprint, avoiding interference with other hardware components such as video cards or heatsinks.
