DiGiYes 5Pcs NRF24L01 2.4GHz RF Wireless Data Features
-
NRF24L01 is a monolithic transceiver working in the 2.4 - 2.5GHz universal ISM band.
-
The wireless transceiver includes: frequency generator, enhanced SchockBurstTM, mode controller, power amplifier, crystal amplifier, modulator and demodulator.
-
Output power channel selection and protocol settings can be set through SPI interface.
-
Low current consumption. When working in the transmit mode, the transmit power is 6dBm, the current consumption is 9.0mA, and the receive mode is 12.3mA. In the power down mode and standby mode, the current consumption is lower.
-
Low working voltage: 1.9 - 3.6V.
About DiGiYes 5Pcs NRF24L01 2.4GHz RF Wireless Data
Features: - High speed rate: 2Mbps. Because the air transmission time is very short, the collision phenomenon in wireless transmission is greatly reduced (the software sets the air transmission rate of 1Mbps or 2Mbps). - Multi frequency point: 125 frequency point, meeting the requirements of multi-point communication and frequency hopping communication. - Ultra small: built-in 2.4GHz antenna, compact size, 15 x 29mm (including antenna). - Low power consumption: when working in response mode communication, fast air transmission and startup time greatly reduce current consumption. - Low application cost: NRF24L01 integrates all high speed signal processing parts related to RF protocol, such as automatic retransmission of lost data packets and automatic generation of response signals. The SPI interface of NRF24L01 can be connected using the hardware SPI interface of the microcontroller or simulated using the I/O interface of the microcontroller. The internal FIFO can interface with various high and low speed microprocessors to facilitate the use of low-cost microprocessors. - Easy to develop: Because the link layer is completely integrated on the module, it is very easy to develop. Automatic retransmission function, which automatically detects and retransmit lost data packets. The retransmission time and retransmission times can be controlled by software to automatically store the data packets that have not received the response signal. After receiving valid data, the module automatically sends the response signal, There is no need to program carrier detection separately - fixed frequency detection built-in hardware CRC error detection and point to multipoint communication address control packet transmission error counter and carrier detection functions can be used for frequency hopping settings. Six channel receiving channel addresses can be set at the same time. The standard pin Dip 2.54mm spacing interface of the receiving channel can
