The I2C/TWI Communication shield module is mainly used and made for the nRF24l01 transceiver module, dedicated to providing reliable performance and reducing the possibility of data lost in the communication process there are three stages to process communication on this module.

How does it work?

1. This module uses the I2C/TWI Communication protocol which simplifies the nRF24l01 communication process stable, thus users no need to understand the communication process of nRF24l01, which improves the efficiency of project development.
2. This module will be used as a slave of I2C/2WI at the address 35
3. It has smooth bidirectional communication and is not discernable at the slave or the master.
4. It has a maximum transmission distance that can reach 70m it depending on the module you use.
5. nRF24l01 communication protocol will reduce the signal loss.
6. 12C/TWI protocol simplifies the communication line.
7. Perfectly compatible on Arduino.

Technical Details

  • Operating voltage: 5V
  • Hold time of Module receives the data:more than 2S
  • Hold time of Module sends 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)


  • This module can be use in Robot Control System, Remote Control. Etc, this device is not recommended for life protection, it is using wireless radio communication may provide a radiation.
  • This device operates on 5v and it has no short-circuit protection, so you must be careful with polarity.
