DMM Shield: 7-Function Digital Multimeter Shield
The DMM Shield brings the functionality of a digital multimeter to a convenient shield form factor. Complete with FPGA and microcontroller libraries, the DMM shield can be integrated into designs and communicated via a custom SPI protocol. It is a 5 1/2 digit digital multimeter, with hardware designed for use with select Arduino Boards, Digilent's line of microcontroller boards such as Uno32™, uC32™, WF32™, or Max32™ and FPGA boards that are equipped with the Arduino shield header such as Arty A7, Arty Z7-10, Arty Z7-20 or Arty S7. The libraries and out-of-box material are written for the Uno32™, uC32™, WF32™, Max32™, Arty Z7-20, Arduino Uno, Arduino Due, and Arduino Mega.
The shield is built around the HY3131 module from Hycon Technology, which is an analog front-end DMM dedicated chip. The device has 7 measurement functions and is factory calibrated. It can be used out of the box with the compatible system boards line.
