Compact Electronic Pen for Interactive Whiteboards

The SPECIAL PIE SP-EA is a lightweight plastic pen designed for portable interactive whiteboard systems. It uses 850nm LED movement detection technology to enable writing and control on any projection surface. Weighing just 25g, it is built for comfortable handling during extended sessions.

Suited for Educators and Presenters

Teachers and trainers who need a cordless pen with a built-in hanging ring for quick access will find this model practical. The third-generation design includes an internal lithium battery, removing the need for disposable cell swaps. Buyers who require the included AAA5 power source or a different wavelength should consider other options.

850nm LED Detection Wavelength

The pen operates at a fixed 850nm wavelength, which must match the receiver specifications of the whiteboard hardware. Standby time reaches 60 days on a full charge, supporting infrequent use without constant recharging. Verify that your portable whiteboard system is calibrated for this exact wavelength before purchasing.

Questions about this item

How long will the included AAA batteries last before I need to replace them?

The pen runs on two AAA batteries that deliver up to 60 days of standby time, so replacement depends on how often you use the interactive whiteboard each day.

What is the first limitation I will hit if I use the pen continuously for hours?

Continuous operation draws from the two AAA cells until they are depleted; the 60‑day standby figure does not apply during active use, so battery life becomes the limiting factor.

Does the pen get warm or make noise after being left on all day?

The plastic body houses only an 850 nm LED and simple electronics, so it stays cool and silent even during extended sessions.
