Introdução
The daughterboard serves as a secondary circuit board that handles key input/output functions like the power button, USB ports, and SD card reader. It also communicates with the motherboard through a flex cable which ensures efficient data transfer. The daughterboard can stop working by wear from frequent use, physical damage on ports, or flex cable having issues.
