1 E511 Overview

1.1 Introduction

This kit is designed for the evaluation and development of applications using the QT511-ISSG
QWheel™ IC. The kit includes an evaluation assembly (E511 – see Figure 1), cables and QWheel
software. The E511 has a serial interface allowing connection to a PC for control and data viewing via
a USB to SPI adapter card and QWheel PC software.

This unique IC allows designers to create speed or volume controls using a wheel/rotor and other
more exotic forms of human interface on the panel of an appliance or personal electronic device.
Generally it can be used to replace any form of rotary knob, through a completely sealed panel.

Refer also to the QT511-ISSG datasheet.

1.2 Contents of Kit

1 x E511 evaluation assembly, fitted with conductive backplate
1 x E511 evaluation board (complete with components and self-adhesive on one side)
1 x USB-PC cable
1 x USB-SPI adapter card
1 x 14-way flat flexible cable (FFC)
2 x sample QT511-ISSG ICs
1 x CD-ROM containing QWheel software, User Manual and Datasheet

2 Mounting the Spare E511 Board

A spare E511 board is included to allow testing on different applications. It can be adhered to plastic,
glass, or any other dielectric panel. Follow these steps to attach the E511 board and refer to Figure 2:

1. Use ESD precautions when working with the E511 board.

2. Remove the paper backing from the E511 board and adhere the board to the rear of the dielectric
panel. Bend the board slightly

Note: The board does allow some flexing, but care must be taken not to bend it too far as this can
crack the SMT components.

Also, the four corner M3 threaded fasteners are connected to ground on the board.

, while smoothing it to remove any air bubbles.

remove the backing paper bend the board slightly
