Evaluation Kit for the MAX35103/MAX32620

Please check latest availability status for a specific part variant.


The MAX35103EVKIT2 provides an application example using the MAX35103 time-to-digital converter to measure water flow as part of an off-the-shelf residential irrigation system. The kit includes a PCB and ultrasonic transducer assembly that can be added to standard 24VAC irrigation systems to provide enhanced shut-off irrigation control.

The kit features a MAX32620 Arm® Cortex®-M4 low-power MCU that executes application firmware. Debug support is provided by a 10-pin JTAG connector and a 3.3V TTL UART connector. Future Mbed™ support is provided by the included MAX32625PICO module.

The kit is designed to be inserted between a 24VAC irrigation controller and an irrigation valve. The valve and controller are optional and are not included but can easily be obtained at most home improvement retailers.
