1. Product Overview
The product is a rechargeable active capacitive stylus with a built-in microphone and a Bluetooth Low
Energy (BLE) transceiver. It is used to write and draw on iPad (iPadOS) capacitive touch screens and
to record voice, for example in meetings and lectures.
The pen connects to the APP on the iPad over Bluetooth Low Energy (2.4 GHz, BLE only).
Recordings are uploaded by the APP to a cloud service and returned as text transcription, translation,
summary and mind map. The pen itself has no Internet connection; its 2.4 GHz radio is used only for
the Bluetooth communication between the pen and the iPad.
Main functions:
•
Writing and drawing on iPad
•
Voice recording with the built-in microphone (double click the key to start / stop)
•
Long press the key for about 2 seconds to switch the pen on / off
•
Automatic power off after 5 minutes without operation (not during recording)
•
Bluetooth Low Energy link to the APP for writing data, control commands and audio files
•
APP functions: transcription, translation, summary, mind map
