A debugging module for connecting an IC to a JTAG debugger device includes a JTAG interface, an earphone circuit, a USB interface, a switching unit, and a reset circuit. The earphone circuit is electrically connected to the JTAG interface via the switching unit. The USB interface and the reset circuit are electrically connected to the JTAG interface. When a JTAG debugger device is connected to the earphone circuit and the USB interface, the earphone circuit and the USB interface, respectively, can establish a connection between the JTAG debugger device and the JTAG interface.
