Application Note AS3932 Description of Demosystem
1 Introduction

The demo-kit consists of a AS3932 LF wake-up receiver board, a 3V CR2032 Lithium Battery, a LF transmitter board and a 9V power supply. The power supply cable is not included and has to be chosen according to the specific plug depending on the country .

The receiver board supports 3-dimensional field detection and can show the main functionality of the AS3932. The receiver board can work completely stand alone in fact neither power supply nor a PC are needed. It is possible to see the AS3932 main functionality just operating the switches present on the board. The chip will be programmed using a microcontroller.

The transmitter board generates the field capable to wake the receiver up. Even this board does not need any PC connection but has to be supplied by the included power supply.
2 Overview of the RX board

The receiver board RX-Board consist of an AS3932 LF-Wakeup receiver, a microcontroller for programming the device, a set of 3-dimensional coils XYZ, a main switch, 2 pin connectors shorted with a jumper where to measure the current consumption of the AS3932 , a set of 4 pin connectors where to monitor the out coming signals of the AS3932, a bank of 8-dipswitsches for the AS3932 programming, 4 buttons SEND, CL_W, R_RSSI, CL_F , 3 LED arrays 5 LEDs each showing the RSSI of each channel, 3 LEDs showing the active channels and a holder for a CR2032 Lithium battery.
