SI24R1 and NRF24L01+are completely compatible (SPI operation timing, register definition, working status diagram), can communicate with each other, support all communication functions of NRF24L01+.

NRF24L01 is a single-chip transceiver chip working in the 2.4-2.5GHz world general ISM frequency band. Wireless transceiver includes: frequency generator enhanced SchockBursttm mode controller Power amplifier Crystal amplifier Moder Dormators Output power channel selection and protocol selection and protocolThe setting can be set through the SPI interface to set up extremely low current consumption. When the work is launched in the launch mode, the current consumption is 9.0mA accepting mode to the 12.3mA power loss mode and the current consumption mode is lower in the standby mode.

The ball opens the ISM frequency band, with a maximum 0dbm transmission power, and is exempted from the license.Empty 180-240 meters!

Compared with imports and imports, it definitely exceeds the import of imports!

There is a Potter rate of 250kb in open conditions, and there are signals above 240 meters.At this time, the directionality is extremely strong, but the 2.4G winding and penetration are not strong. This is the disadvantage, and I must explain.Everyone is the same!

Data receiving support for the sixth road channel

1. Low -working voltage: 1.9 ～ 3.6V low voltage work

2. High rate: 2Mbps, due to the short transmission time in the air, it greatly reduces the collision phenomenon in wireless transmission (software settings 1Mbps or 2Mbps air transmission rate)

3. Multiple frequency points: 125 frequency points to meet multi -point communication and frequency -jump communication needs

4. Ultra -small: Built -in 2.4GHz antenna, small volume, 15x29mm (including antenna)

5. Low power consumption: When the work is communicated in the response mode, the fast air transmission and startup time greatly reduces the current consumption.

6. Low -application cost: NRF24L01 integrates all high -speed signal processing parts related to the RF protocol, such as: Automatic redevelopment of lost data packets and automatic answering signals.The I/O port is simulated. There is an interface with various high and low -speed micro -processor interfaces internally, which is convenient for low -cost single -chip microcomputers.

7. Convenient development: Since the link layer is completely integrated on the module, it is very convenient for development.Automatic re -issuing function, automatic detection and reworting the loss of data packets, reassess time and re -issuing number can be controlled by the automatic storage data packet that does not receive the answer signal automatic answer function. After receiving the valid data, the module automatically sends the response to the response to the response.Signal, there is no need to program another carrier detection -fixed frequency detection of built -in hardware CRC detection error and point -to -point communication address control data packet transmission error meter and carrier detection function can be used to set the six -way receiving channel address at the same time. It may be selective.Open the PR Periodic Point DIP2.54mm spacing interface to facilitate embedded applications.
