1 Introduction
The WR RF module is a 2.4GHz transceiver.
WR RF module operates in 2.400-2.4835GHz ISM frequency band.
To design a radio system with the WR RF module, you simply need an MCU (microcontroller)
and a few external passive components.
You can operate and configure the WR RF module through a Serial Peripheral Interface (SPI).
