INTRODUCTION
The SX1239 PICtail™ Receiver Daughter Board is a demonstration and development
platform for wireless security remote control applications. This section gives a detailed
description of the receiver daughter board.
HARDWARE DESCRIPTION
Figure 4-1 shows the SX1239 Receiver PICtail Daughter Board. The schematic, PCB
layout, and Bill of Materials are listed in Appendix B. “SX1239 Receiver PICtail™
Daughter Board Schematics”.

The daughter board features the Semtech SX1239 Low-Power Integrated UHF
Receiver (http://www.semtech.com/wireless-rf/rf-receivers/sx1239/). The PICtail
daughter board can plug into the 28-pin PICtail connector featured on many Microchip
Technology development tools.
The antenna connection has a pin socket for plugging a wire antenna. This
demonstrates a simple and low-cost antenna option. The length of the antenna should
be approximately ¼ wavelength of the frequency of interest.
