The traditional digital paper is fixed on the soft-written digital handwriting, and combined with the advanced and flexible sensor technology of Junyu, it can accurately track the position of the stylus on the paper. The position information is combined with the built-in pressure sensor circuit of the stylus. It can monitor 2,048 pressure points and accurately capture all handwriting.
Every time the user drops the pen, Nordic Technology helps the low-latency, low-power Bluetooth connection to wirelessly transmit information to a paired Bluetooth 4.0 (or higher) iOS or Android smartphone or tablet to digitally reproduce and save images.
Users can edit, enhance or delete these saved images with the softmail app installed on their smartphone, and then instantly share them with friends, colleagues or customers. In the absence of a receiver, users can store handwritten content in numbers. The 16MB external memory on the handwriting is transferred to the mobile device later.
Soft note uses the micro-USB charging interface, provides 30 days of battery life in standby mode, and 8 hours of continuous battery life, and one of the reasons for its low power consumption is the low power consumption of the nRF52832 SoC. Designed with a 2.4 GHz RF component with a peak RX / TX current of 5.5 mA, its fully automated power management system minimizes power consumption.
Nordic's nRF52832 multi-protocol SoC device integrates a 64MHz, 32-bit Arm® CortexTM M4F processor with 2.4GHz multi-protocol RF components (supporting Bluetooth 5, ANTTM and proprietary 2.4GHz RF software) with -96dB receiver sensitivity, and 512kB Flash memory and 64kB RAM.
The SoC device is equipped with Nordic's S132 protocol stack and Bluetooth 5 certified RF software protocol stack for building advanced low-power Bluetooth applications. The S132 protocol stack supports Central, Peripheral, Broadcaster and Observer Bluetooth low-power roles. Achieve up to 20 connections and parallel role operations.
