Nrf24l01 Schematic. These modules are very cheap and you can use them with any microcontroller mcu. One thing to remember is it is a half duplex type that means it can either send or receive data at a time.
They operate in the frequency of 2 4ghz which falls under the ism band and hence it is legal to use in almost all countries for engineering applications. This one is commonly used in commercial modules based on this chip. These modules are very cheap and you can use them with any microcontroller mcu.
They are transceivers which this means that each module can transmit and receive data.
Nrf24l01 is a single chip radio transceiver for the world wide 2 4 2 5 ghz ism band. Output power frequency channels and protocol setup are easily. Nordic nrf24l01 integrates a complete 2 4ghz rf transceiver rf synthesizer and baseband logic including the enhanced shockburst hardware protocol accelerator supporting a high speed spi interface for the application controller. The circuit contains some decoupling capacitors connected between vdd and ground.
