Stylus pen Acer ASA410 — active AES 2.0 / USI 2.0 / MPP2.5, universal, black, 16.5 g

The Acer ASA410 active stylus pen is a universal input tool designed for compatible tablets and laptops. Supporting AES 2.0, USI 2.0 and MPP2.5 protocols with backward compatibility, the pen switches protocols via button press and holds. It has a compact 9.5 mm body diameter, weighs 16.5 g and is finished in black for a discreet appearance. The stylus offers high precision for note-taking, sketching and detailed touchscreen control without the need for manual pairing on supported devices.

Advantages

The ASA410 provides broad device compatibility across multiple active stylus protocols, enabling use with a wide range of touch devices. It delivers natural pen-like input with 4,096 pressure sensitivity levels, tilt support and a responsive tip force range for smooth strokes and accurate pressure detection. Its featherlight construction reduces hand fatigue during extended use, while operation from a single AAAA battery yields long standby times. The pen’s plug-and-play behaviour requires no complex setup on supported systems, allowing immediate writing or drawing.

Suitable for

• Taking handwritten notes on compatible tablets and convertible laptops
• Sketching and digital illustration that require pressure sensitivity and tilt
• Precise navigation and annotation of documents and PDFs
• Education and classroom use with devices supporting AES, USI or MPP protocols

How to use

Hold the stylus as you would a regular pen and apply pressure to write, draw or navigate on a compatible touchscreen. To change the active protocol, press and hold the pen buttons until the desired protocol is selected; the ASA410 supports AES 2.0, USI 2.0 and MPP2.5 and will work with older versions via backward compatibility. The device is designed for plug-and-play operation on supported hosts, so in most cases no pairing or driver installation is required. Replace the AAAA battery when responsiveness decreases.

Usage recommendations

For best precision and tip longevity, use the stylus on clean, undamaged screen protectors or directly on the device display as specified by the device manufacturer. Store the pen in a dry place and avoid dropping it to preserve tilt calibration and tip condition. If pressure sensitivity or tilt response changes, check the battery level and replace the AAAA cell as needed.
