The DK-CH101 is a comprehensive development platform for MOD_CH101, a miniature ultrasonic transceiver with a range of 4cm to 120cm.

Part of the SmartSonic platform, the DK-CH101 is designed around Atmel’s SAMG55 MCU can be used by developers for rapid evaluation and development of MOD_CH101 based solutions. The DK-CH101 includes an on-board Embedded Debugger so external tools are not required to program or debug the SAMG55 MCU.

The development kit comes with necessary software including SonicLink, a GUI based development tool and embedded drivers for MOD_CH101.

SonicLink is a GUI based development tool included with the platform. It can be used to capture and visualize the sensor data from the ultrasonic transceiver.
