A mobile terminal for PCB revision management is provided to efficiently perform software management, sample management, ERP management, and A/S management by simply confirming PCB revision information through voltage injection only without disassembling the external case. A mobile terminal for PCB revision management is comprised of a keypad part(100), a pull-down part(200), and a control part(300). The keypad part(100) receives key input. The pull-down part(200) is installed at the input stage of the keypad part(100). If a revision information confirmation request is made, the control part(300) supplies a high-level signal to the pull-down part(200), checks the current flowing on the pull-down part(200), judges revision information using the checked current value, and displays it on the idle screen before booting.
