NRF24L01+ wireless data transmission module 2.4G ATMEGA48+ NRF24L01 for Arduino compatible


RADIO MODULE FOR NRF24L01
1. Module Features:
1) using I2C (TWI) communication protocol, which greatly simplifies the NRF24L01 communication process,
Users do not need to understand NRF24L01 cumbersome communication process, which greatly improves the project development
Efficiency.
2) Each module is as I2C (TWI) slave (address 35)
3) module is small and long 73mm wide 22mm
4) smooth two-way communication, regardless of the slave and master.
5) Maximum transmission distance can reach 70m (for production test)
6) wireless communications chip NRF24L01 reliable communication protocol, reducing data loss
7) I2C/TWI protocol greatly simplifies the communication lines,
8) perfectly compatible with arduino

Related terms:
The transmission data holding means when the module (TWI slave) receives data sent to the host after the data is transmitted to another module, and then waits to receive another response signal of a module , if the waiting time is still no general acknowledge signal. Then module will re-send the data out, repeatedly send data wait time is multiplied by the number of module sends data hold time
Module receives the data hold time is when the module (TWI slave ) receives NRF24L01 pass over the data immediately shielded NRF24L01, the system jumps to wait for the host to take over the data , the maximum waiting time is to receive data hold
