RF module is connected in expansion connector and it is very easy to use with
mOwayGUI. The best way to start working with the module is using an example project
provided in mOwayPack.

The
BZI-RF2GH4
radio-frequency communications module is based on the
nRF24L01 transceptor manufactured by “Nordic Semiconductors”. This integrated
circuit has been fitted with all the logic required to establish wireless bidirectional
communications with acknowledgement of receipt. Communications with the
microcontroller is made via an SPI bus.
The main characteristics of the BZI-RF2GH4 module are as follows:
•
Low consumption.
•
Working frequency: 2.4GHz,
•
Transmitting power between-18 and 0 dBm,
•
Transmission speed between 1 and 2 Mbps,
•
128 in transmission channels selectable by the SPI bus.
In addition to the CI nRF24L01, the
BZI-RF2GH4
is also fitted with all the
associated electronics for its correct operation plus a microstrip antenna on the same
board with the impedance adaptation network. In this way the user can forget
completely about the hardware required to implement the radio part of his application.
As interface, the device has four pins available for the SPI bus, two more pins for
controlling the module and another two for the supply.
In order to facilitate the handling of the module, a number of libraries have been
developed to simplify and shorten the development time of wireless applications with
these modules.
