Technology

Multi-channel audio pickup with high sound quality
It can obtain 192-kHz/24-bit high-resolution audio and vibration data, beyond the limits of human recognition. It can also simultaneously capture synchronized audio from up to four channels with an analog microphone or eight with a digital microphone. With signal processing and AI processing through high computing capabilities using its multi-core processors, enables sensing beyond what humans can perceive.

High computing capabilities at low power
It has a hexa-core structure comprising six Cortex-M4F processors. By using a cutting-edge silicon process to significantly reduce the drive voltage, it achieves power consumption that is even lower than standard multi-core processors. Its CPU power, clock, and memory are also all designed for operation under optimal low power conditions, achieving low power even on the system side. It also has a camera and voice input/output to utilize images and audio in applications with low power consumption.
