Analog Devices MAXREFDES72# Operating instructions

  • Hello, I'm a chat assistant. I've reviewed the MAXREFDES72# Quick Start Guide. This document details how to configure the MAXREFDES72 adapter for mapping Arduino headers to a Pmod connector. It highlights features like arbitrary pin mapping and support for various Pmod types. I’m ready to help with any questions you have about this device.
  • How is the MAXREFDES72# board configured?
    What types of Pmod connectors are supported?
    Is any configuration needed for Type 1 and Type 2 Pmod connections?
    What is the function of the MAX14661 multiplexer?
