USB2GPIO# Adapter Board

General Description

The USB2GPIO# adapter board is designed to work

with Maxim’s Munich GUI and to connect to various EV

kit or Pmod boards with Pmod™ compatible connectors

different Maxim ICs. This document explains how the

USB2GPIO# adapter board receives commands from

interface. The Maxim USB2GPIO# board requires the

Munich GUI which can be downloaded from Maxim’s

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

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

fully compatible with previous adapters and low-pin count

EV kit or Pmod boards. This connector is controlled from

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

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

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#. Note that an “EV system” is an EV kit

combined with an interface board, such as a USB2GPIO#

and EV kit GUI software. Ordering information for EV

systems is included in the EV kits’ corresponding data

sheet. Refer to the appropriate EV kit data sheet for quick

start and detailed operating instructions.

Windows 8, and Windows 10 system using Munich GUI,

Version 2.17 or later.
