GWT154 WIRELESS TRANSCEIVER APPLICATION CIRCUITS
The Radio Module is a standalone RF module with an optional external dipole antenna. It is intended
to be an RS-485 cable replacement for new GTECH embedded applications or as an OEM replacement
module for our suppliers of GTECH equipment.
For existing or legacy GTECH products, the Radio Module should be mounted to the Host Board via
the two 1x10 headers. These mated boards are enclosed in a plastic housing and this constitutes the
Dongle solution.

Electronics
Overview
The electronic design solution for this product consists of two PC boards.
Radio module. This stand-alone module will be the solution for new embedded designs
or for an OEM module replacement. The two 1 x 10 pin headers will be the interface to
the radio module for all configurations. The radio module will consist of the Texas
Instruments CC2530 SOC, the Texas Instruments CC2591 Front end module, a
Johanson 2450AT18A100 chip antenna, and a Hirose U.FL coaxial RF connector.
A host board will consist of the GTECH RS-485 interface, USB 2.0 interface, DC
power jack, and interface connectors to plug the radio module into. The combination of
these two boards with the plastic enclosure will provide the solution for the dongle.
