Palm V/Vx IrDA Enhancement
(12 June 2001)


The Palm series uses the "MiniSIR2" IrDA module
for Infra-Red communications.

The original circuitry for the IrDA module is as follow.
Pin 1 of the module is connected to a 15 ohm
resistor as current limiter.

The resistor is marked as "150" on the PCB.

Change this resistor to 3 - 5 ohm (I use a 3 ohm).
The firing range increased from 3-5 feet to 10-12 feet!

The PCB at a closer look.
