NRF24L01
NRF24L01 is a job at 2.4-2.5 GHz world general ISM band single-chip transceiver chip, wireless transceiver including: frequency generator enhanced SchockBurstTM mode controller power amplifier modulator crystal amplifier output power of the modem choice and agreement of the channel set can be through the SPI interface setting very low current consumption, when work in launch mode transmit power for six dBm current consumption is 9.0 mA when accept mode for 12.3 mA power lost mode and standby mode current consumption model is lower.
The ball open ISM band, the biggest 0 dBm transmission power, free use license. Open 100 meters!
All the data receiving support channels
1. The low voltage: 1.9 ~ 3.6 V low voltage
2. The high rate: 2 Mbps, because the air transport time is very short, greatly reduced the wireless transmission of collision phenomenon (software set to 1 Mbps or 2 Mbps air transmission rate)
3. Many frequency: 125 frequency, meet more communication and frequency hopping communication needs
4. Mini: the built-in 2.4 GHz antenna, volume is small and exquisite, 15 x29mm (including antenna)
5. Low power consumption: when work in response patterns communication, fast air transport and start time, greatly reduce the current consumption.
6. Low application costs: NRF24L01 integrated all and RF agreement to speed signals processing, such as: automatic heavy hair loss packet and automatically generated response signal etc, the NRF24L01 using single chip computer interface can SPI hardware SPI mouth connection or by single chip I/O mouth is simulated, the FIFO and all kinds of high or low speed can be microprocessor interface, easy to use low cost microcontroller.
7. Easy to develop: because the link layer in fully integrated on the module, which is convenient for development. Automatic heavy hair function, automatic detection and heavy hair loss of data packets, heavy hair time and heavy hair times can control software automatic storage not received response signal packets to be automatic response function, in the received data effectively, module automatically send response signal, need not be programming carrier testing-fixed frequency detection built-in hardware CRC inspection wrong and point-to-multipoint address control data packets error counter and carrier testing function can be used for frequency hopping set set at the same time all receive channel address, can have selective open receiving channel standard needle inserted Dip2.54 MM spacing interface, easy to embedded applications.
