While working on electronics and searching many tools and modules to work on , we have always been looking for some wireless module which can perform few operations on its own and do not need any extra micro controller for that . Have you had the same thought ? While searching for latest RF technologies ,we got to heard about the NRF24LE1 modules . After working on it at EG Labs , we found that it is a very interesting module and every electronics hobbyist must give it a try once in their electronics projects.
Introduction to the module
NRF24LE1 is a 14 pin module , manufactured by Nordic Semiconductors Ltd. The main thing which left us awestruck is that the module has inbuilt 8051 based Microcontroller . This means we can code this module as per our need . Along with 8051 controller ,the module provides 2.4GHz RF transceiver and uses GFSK modulation which gives it the power to communicate wirelessly with as far as 100 meters without noise.
The NRF24LE1 comes in three packages which are 24-pin, 32-pin and 48-pin package. We will be using 32-pin package in our present series. This package contains 15 I/0(input/output) pins. These 15 pins are also used for communications like UART, I2C or features like PWM and ADC. The module is self biased and the remaining 17 pins are used for antenna, crystal oscillator,biasing etc.
