2.4G NRF24L01

Product parameters:
Onboard 2.4G PCB antenna, ISM band, 2.54mm pin DIP8 package, compact size, easy to use for embedded applications.

Support six-channel data reception (one pair of six)

Support GFSK modulation

Supports 2Mbps/1Mbps/250Kbps data rate, and can set different transmit power

Multi-frequency point: meet the needs of multi-point communication and frequency hopping communication, 2400MHz~2527MHz, 1MHz frequency hopping stepping

Internally integrated high PSRR LDO

Wide supply voltage range: 1.9~3.6V, typical 3.3V

Average emission current as low as 18mA (4dBm)

Receive sensitivity: -96dBm@250kbps

Transmit power up to 4dBm

4-wire SPI interface with 8MHz speed

Internal packet processing engine

Transceiver data hardware interrupt output

Working temperature: -20 ° C ~ 85 ° C

The best transmission distance: less than 120 meters (250kbp open environment without shielding without electromagnetic interference) reliable distance recommended to use within 30%-50%

Note:
When connecting with the P0 port of the 51 series MCU, it is necessary to add a 10K pull-up resistor, which is not required to connect with the remaining ports.
For other series of single-chip microcomputers, if it is 5V, please refer to the output current of the IO port of this series of microcontrollers.
If it exceeds 10mA, it needs to be divided by series resistors, otherwise it will easily burn the module! If it is 3.3V, it can directly connect with the IO port of nRF24l01 module.
Wire connection, such as AVR series MCU.
The module's SPI rate can only support up to 8M, which is generally recommended at 1M or a few hundred K SPI rate.
