It will be ubiquitous in a future network of things, and widely used in military and everyday life. In this paper, based on the radio frequency chips NRF24L01, and discussed the methods and processes of the design of the configurable wireless communication module based on the ATMEGA8 microcontroller. After understanding function of the chip works, finished the schematic design of the configurable wireless communication module and PCB drawing. After reading the data sheet of the ATMEGA8 microcontroller and NRF24L01, used the ATMEGA8 microcontroller to deploy NRF24L01 relevant register, achieved variable configuration of the inter-node communication frequency, the data transfer rate, the RF module transmit power and transmission packet length, which make each node has a high flexibility characteristics, and improved anti-jamming capabilities. The configurable wireless communication module with small size, low power consumption, low price, is more convenient than wired systems on the market to achieve deployment function, and certainly have a vast market space.
