VDrive3 Vinculum-II

Application Module

VDrive3 is a USB host/microcontroller application module with an enclosure. The default

firmware of the VDrive3 supports UART/SPI communications with the embedded USB host

controller and USB host port. This product provides an attractive solution for quick and

easy integration of applications with a USB flash disk or other USB client devices.

Introduction

VDrive3 is designed to support quick and

easy integration of a UART/SPI application

with a USB client device. The VDrive3

comes in a neat enclosure displaying a bi-

colour LED, making it suitable for

incorporating into finished product designs.

In addition, a product option, VDrive3-LD, is

available that offers a lid to cover the USB

port to provide protection in harsh

environments.

The VDrive3 utilises FTDI’s Vinculum-II

(VNC2-48L1B) dual USB host controller IC.

This IC is a microcontroller and USB host

controller; it is reprogrammable using the

UART interface or the Vinculum-II debugger

module connecter. The default firmware is

V2DAP; this firmware establishes the

UART/SPI to USB host interface and can be

modified or replaced with other firmware.

V2DAP is firmware that supports Vinculum-

II to Vinculum backward compatibility*. The

Vinculum-II IDE and FTDI’s expanding

range of drivers allow for additional design

flexibility (including Android interfacing).
