The "Lenovo Pen Pro for Googlebook," a stylus pen that Lenovo is preparing as one of its peripherals for Googlebook, has been confirmed to be registered with the Bluetooth SIG.
On the Bluetooth SIG product list, the "Lenovo Pen Pro for Googlebook" is listed as an "Active Stylus" with the model number "SE01." This matches the model number previously confirmed in the FCC filing.
Specifications Confirmed in FCC Filing
Although the Bluetooth SIG registration does not reveal any new information, the "Lenovo Pen Pro for Googlebook" was registered with the FCC on July 7, 2026, under the model number "A5M-SE01." The application documents confirm that the stylus adopts the USI standard, supports magnetic attachment, and features wireless charging.
According to the manual, the pen tip supports clicking, tapping, and writing on the screen, while the pen top features an eraser function. It is also equipped with a side switch that supports the following gestures:
-
Single tap with the pen tip: Select/open an item
-
Double tap the side switch: Take a screenshot
-
Hold and release the side switch, then encircle content on the screen: Search
-
Swipe up or down on the side switch area: Scroll up or down a page
-
Press and hold the side switch area for a few seconds: Initiate Bluetooth pairing
Among these gestures, the feature to search by encircling content may correspond to the "Circle to Search" feature.
Furthermore, the manual includes a diagram illustrating the pen magnetically attaching to the back of the device. The design of the back and the camera section matches the leaked images of the Lenovo Googlebook Duet m (13”, 11) from early August. This also indicates that the "Lenovo Pen Pro for Googlebook" is intended for the Lenovo Googlebook Duet m (13”, 11), codenamed Sapphire.
Although Lenovo has not yet made an official announcement, it is expected to be unveiled at the upcoming IFA 2026. Additionally, with Google hosting a Googlebook media event in the US on September 15, the pen, along with other devices, is anticipated to be announced soon.
In addition to the stylus pen, Lenovo is also preparing the “AI Mouse M830” designed for Googlebook.
