This development board uses the ATmega48 microcontroller for convenient interfacing with the NRF24L01 module. It also features an I2C communication interface that can be used for communication with other microcontrollers such as Arduino or for connecting other peripherals directly to this board. This module comes programmed with an I2C to SPI bridge which implements a convenient RF communication solution. With this module, users do not need to understand the NRF24L01 communication protocol which makes the building of NRF24L01 wireless application easier. This improves the efficiency of the project development process. This module is perfect for robots, remote controls, and remote sensing applications. Specifications Operating Voltage: 5 V (No short-circuit protection) Transfer Rate: 50 Bytes/second I2C/TWI Address: 0x47 (decimal 35) NRF24L01 Address: 0x34, 0x43, 0x10, 0x01, (from low to high)
