Evaluates: USB2GPIO USB2GPIO Adapter Board General Description Features 2 The USB2GPIO adapter board is designed to work USB-to-I C/SPI/GPIO Interface with Maxims Munich GUI and to connect to various EV Small PCB area kit or Pmod boards with Pmod compatible connectors Pmod-Compatible Form Factor 2 for I C/SPI/GPIO communication to test and evaluate different Maxim ICs. This document explains how the USB2GPIO adapter board receives commands from 2 a laptop through the USB to create an I C/SPI/GPIO interface. The Maxim USB2GPIO board requires the Munich GUI which can be downloaded from Maxims website free of charge. The USB2GPIO design is powered directly from the USB bus power (5V) and integrates two low-power, 1.2A, PWM step-down DC-DC converters (MAX1556) to provide programmable V voltages of 1.8V, 2.5V, 3.3V, or 5.0V. CC A dual, high-speed, USB-to-multipurpose UART/FIFO IC (FT2232HQ), high-speed USB switches (MAX4983), and a 4K MICROWIRE-compatible serial EEPROM are the other ICs on this adapter board. USB2GPIO is designed to supersede USB2PMB1 and USB2PMB2 adapters and includes two connectors connector X3 is a 12-pin connector which supports either 2 I C with 6 GPIO pins, or SPI with 4 GPIO pins, and is fully compatible with previous adapters and low-pin count EV kit or Pmod boards. This connector is controlled from Figure 1. USB2GPIO Board the Munich GUI. The addition of another connector, X2, which is a 20-pin connector allows either 16 extra GPIO connections or a second SPI port and 12 extra GPIO connections. This 20-pin connector is NOT controlled by Ordering Information appears at end of data sheet. Munich GUI but is for use with future EV kits and will be controlled by the relevant EV kit GUIs. This USB2GPIO adapter board can be used to enable 2 USB-to-I C/SPI interface for any Pmod-compatible plug-in peripheral modules such as the Maxim MAX14001PMB , and MAXREFDES12 Corona reference designs. In addition, it can be ordered together as an evaluation system (EV system) with different EV kits, such as MAX14001EVKIT .

Refer to the appropriate EV kit data sheet for quick start and detailed operating instructions. The USB2GPIO has been tested on Windows 7, Windows 8, and Windows 10 system using Munich GUI, Version 2.17 or later. 319-100131 Rev 0 1/18Evaluates: USB2GPIO USB2GPIO Adapter Board temporary folder and decompress the Munich GUI- Quick Start SetupV2.17.zip file. Required Equipment 2) Connect the USB cable between the USB2GPIO PC with Windows OS (Windows 7, Windows 8, or board and the PC the USB driver is installed Windows 10) with a USB port automatically. 3) Ensure that the companion SPI interface devices USB2GPIO board jumper settings are correct. Refer to your companion A-to-Micro-B USB cable (not supplied) devices documentation.
