The EVKit is manufactured in three parts, consisting of a mainboard, and three separate plug-in module boards. To adjust IC OTP settings, the main board can be interfaced to any personal computer with the Azoteq Configuration Tool (CTxxx), and making the adjustments by means of the USBProg software. The purpose of the IQS232/43EV02 EV-Kit is to help application and development engineers in evaluating the IQS232 and IQS243 proximity and touch sensors. 2 EV-Kit Mainboard Figure 2.1 illustrates the evaluation kit mainboard and the three supplied controller modules. The mainboard supplies power and other functions to the controller module boards and is easily operated. Simply plug in the desired module board into the mainboard and turn on the mainboard by means of the on/off slide switch. Features included in the EV-Kit mainboard: Modular design: Connect one of the supplied IC modules into the mainboard, or wire into a prototype for rapid prototyping Reference designs for IQS232 and IQS243 with user proximity & touch detection ability LEDs to indicate proximity AND contact to the buttons for IQS232 Copyright © Azoteq (Pty) Ltd 2012.

Figure 2.1 IQS232/43EV02 Mainboard and controller modules Can be used in Data Streaming Mode: For details see the IQS232 and IQS243 datasheets (EV-KIT requires Azoteq Configuration Tool CT, or Azoteq Data Streamer DS) Can be used in Direct mode (IQS232 only): Battery or USB powered OTP bits can be programmed on the kit (requires CTxxx) Figure 2.2 illustrates the bottom view of the EV-Kit mainboard. The EV-Kit is powered by two 3V coin cell batteries in series, which is regulated to 3.3V and supplied to the module board. The EV-Kit mainboard can also draw power from a USB source by means of the mini-USB connector provided on the mainboard.
