ATMEGA48 + NRF24L01 + Wireless Shield module SPI to IIC I2C TWI Interface

I2C/TWI Communication Shield Module for nRF24L01

How Does It Work?

1. This module uses the I2C/TWI communication protocol, which simplifies the nRF24L01 communication process. Users do not need to understand the complex nRF24L01 protocol, improving project development efficiency.
2. The module operates as an I2C/TWI slave device with address 35.
3. Supports smooth and stable bidirectional communication between master and slave.
4. Maximum transmission distance can reach up to 70 meters, depending on the nRF24L01 module used.
5. The optimized nRF24L01 communication protocol helps reduce signal loss.
6. The I2C/TWI protocol simplifies wiring and reduces the number of communication lines.
7. Fully compatible with Arduino platforms.
