N2 and M1 + digital pens, although they look like ordinary pens, are technologically advanced devices used to digitize handwriting to digital form.

Pens are equipped with, among others:

• camera that reads the position of the dots from the pattern printed on the pages,
• pressure sensor, which records the pressure and the moment of recording information. Using the pressure sensor, you can also turn on the pen, just touch the tip of the refill on the surface of e.g. a sheet of paper. Please note that recording recording starts in 0.5 seconds,
• internal memory, whose high capacity allows you to store many saved pages,
• battery thanks to which the pen can be used up to 6 hours of continuous writing, and sleeps for many days,
• bluetooth module for communication and data transfer from the pen to the mobile application,
• the USB module is used to charge the pen and transfer data using the IC Pen Receiver application
