Product Introduction

NRF24L01 is a single-chip wireless transceiver chip that operates in the ISM frequency band of 2.4GHz-2.5GHz. The wireless transceiver includes a frequency generator, an enhanced "SchockBurst" mode controller, a power amplifier crystal oscillator, a modulator, and a demodulator.

The selection of output power channels and protocol settings can be set through the SPI interface. It can be connected to almost various microcontroller chips and complete wireless data transmission work.

Product Features

1.2.4GHz global open ISM frequency band

2. Maximum working speed of 2Mbps, efficient GFSK modulation, strong anti-interference ability, suitable for industrial control occasions. 

3. Multi frequency: 125 frequency points, meeting the needs of multi-point communication and frequency hopping communication

4.Built in hardware CRC error detection and point to multipoint communication address control

5. Low power consumption operating voltage of 1.9-3.6V, with a standby mode state of 22uA; 900nA in power down mode

6. Built in 2.4GHz antenna

5. Low power consumption operating voltage of 1.9-3.6V, with a standby mode state of 22uA; 900nA in power down mode

6. Built in 2.4GHz antenna

7. The module can be programmed with software to set the address, and only outputs data when it receives the local address (providing interrupt indication). It can be directly connected to various microcontrollers for easy software programming

8. Built in specialized voltage regulator circuit, with excellent communication performance using various power sources including DC/DC switching power supplies

9.Working at Enhanced Shock Burst with Automatic packet handling, Autopacket transaction handling, Equipped with optional built-in packet response mechanism to reduce packet loss rate

10.When connecting to the P0 port of the 51 series microcontroller, a 10K pull-up resistor needs to be added to connect to the other ports unwanted

11. For other series of microcontrollers, if it is 5V, please refer to the output current of the IO port of this series of microcontrollers. If it exceeds 10mA, a series resistor voltage divider is required, otherwise it is easy to burn out the module! If it is 3.3V, it can be directly connected to the IO port of the RF24101 module. For example, if the AVR series microcontroller is 5V, it is usually connected in series with a 2K resistor
