RCxxxxDK-USB演示板
The Demonstration Kit (DK) is designed to make it easy for the user to evaluate the onboard module, develop an application and build prototypes very quickly. The kit includes two Demo Boards (DB). The demo board contains the selected module with its dedicated article number and embedded protocol and associated support circuits. The board can easily be operated using a PC terminal emulator or the RCTools PC suite from Radiocrafts.
图3.RCxxxxDK-USB演示板外形图
The Demo Board contains USB connector, USB to serial converter, buttons, LEDs, voltage regulator, configuration jumpers and connectors to make it easy to interface the onboard module with various test equipment or the host used in an application. Not all components are needed in an actual application. Please see the datasheet for each specific module for a typical application circuit.
The Demonstration Board comes in different versions, equipped with the different variants of Radiocrafts modules. Among the frequencies supported are 433 MHz, 868 MHz, 915 MHz and 2.45 GHz. For each frequency there exist narrowband versions and wideband versions.
This covers the most used frequency bands, the 433 MHz band in Europe and the US, the 868 MHz band in Europe, the 902-928 MHz band in the US and the 2 450 MHz band worldwide.
The actual module mounted can be seen on the marking on the module itself.
