Product Description:
The NRF24L01 is a single chip transceiver chip that operates in common ISM frequency bands of 2.4-2.5GHz.
1. Low working voltage: 1.9-3.6V low voltage operation
2. High speed: 2Mbps, the air transmission time is very short, so the collision phenomenon in the transmission is greatly reduced (software set the air transmission rate to 1Mbps or 2Mbps).
3. Multi-frequency point: 125 frequency point, meet the needs of multi-point communication and frequency hopping communication.
4. Ultra small: built-in 2.4GHz antenna, small size, 15.2x28.5mm (including antenna)
5. Support 6 channel data reception.
6. Low power consumption: When working with response mode communication, the high speed air transmission and start-up time will greatly reduce the current consumption.
7. ISM frequency band is opened worldwide, the maximum transmit power is 0dBm, no license required.
Low Application Cost:
The NRF24L01 integrates all the high-speed signal processing parts related to RF protocol, such as automatic re-transmit of lost data packets and generate auto-response signals. The SPI interface of the NRF24L01 can be connected with the hardware SPI. The port of a single chip micrometer or the use of a single chip microcomputer is used for simulation, and the interior has FIFO that can interface with a variety of high-speed and low-speed microprocessors to facilitate slow use. Single chip microcomputer cost
EASY TO DEVELOP:
The link layer is fully integrated into the module, making it very easy to develop. Automatic resend function, automatic detection and resend of lost data packets, resend time and resend time can be controlled by software to automatically store data packets that dont receive response signals. Auto-response function will automatically send the module after receiving the valid data. Response signal, no need to program independently career detection—Fixed frequency detection, built-in hardware CRC error detection and point-to-multi-point communication address control data packet transmission error counters and carrier detection functions can be used for frequency hopping settings. 6 receiving channel addresses can be set at the same time and selectable. Open the standard pin Dip2.54MM pitch interface on the receiving channel. It is useful for embedded applications.
