NRF24L01 Wireless Shield SPI to IIC I2C TWI Interface Arduino projects robots NEW

Wireless module for NRF24L01:

I2C (TWI) communication protocol is used, which simplifies the NRF24L01 communication process greatly, users no need to understand the tedious communication process of NRF24L01,it improves the efficiency of project development Immensely by this way.

Each module will be as a slave ofI2C (TWI).(address 35)
Module is in a small frame with length 73mm,width 22mm.
Smooth bidirectional communication and no discernable the slave or master.
Maximum transmissive distance can reach 70m(Just for reference)
Wireless corresponding chip is reliable NRF24L01communication protocol,it will reduce data lost.
I2C/TWI protocol simplifies the communication lines greatly.
Compatible with arduino perfectly.


Robot control, remote control.,Information collection, etc.

Note: The wireless communications may result in radiation, so it is not recommended for life protection area.


Operating voltage: 5V.

(No short-circuit protection,so you must be careful with polarity connection when you use.)

Hold time of module receiving data :more than 2S
Hold time of module transmitting data:more than 300s
Transfer rate:50Byte/S (theoretical value)
I2C/TWI Address:0x47 (decimal 35)
NRF24L01 Address:0x34, 0x43, 0x10, 0x10, 0x01 (from low to high)

Related terms:

Hold time of module transmitting data means when the module (TWI slave) receives data sent from master, it will transmit the date to another module, and then it will wait to receive another responsed signal of that module,if there is no response signal after a while,the module will send the data again,repeated sending times multiply waiting time is the hold time.
