Abstract: A stylus includes a circuit module, a battery module electrically connected to the circuit module, and a fine adjustment module. The circuit module has a circuit board and a variable resistor mounted on the circuit board. The fine adjustment module has a conductor and a conductive refill movably contact with the conductor. The conductor is connected to the circuit board and is electrically connected to the variable resistor via the conductor and the circuit board. The resistance value of the variable resistor can be adjusted to cause the stylus to output a first signal strength through the conductive refill. The conductive refill can be moved with respect to the conductor to enable the stylus to have a signal strength, which is X˜Y % of the first signal strength (80≦X≦100 and 100
