NRF 24L01 Module Long Range
Features :
- NRF24L01 is a universal ISM band monolithic transceiver chip works in the 2.4-2.5GHz
- Wireless transceiver including: Frequency generator, enhanced type, SchockBurstTM, mode controller, power amplifier, crystal amplifier, modulator, demodulator
- The output power channel selection and protocol settings can be set extremely low current consumption, through the SPI interface
- As the transmit mode, the transmit power is 6dBm, the current is 9.0mA, the accepted mode current is 12.3mA, the current consumption of the power-down mode and standby mode are lower
- Built-in 2.4GHz antenna, supports up to six channels of data reception
- Size: 15 x 29mm
- Low operating voltage: 1.9-3.6V
- 125 channels, multi-point communication and frequency hopping to meet the communication needs
- High Rate: 2Mbps, as air transmission time is very short, greatly reducing collision phenomena in wireless transmission (air transfer rate of software setting: 1Mbps or 2Mbps)
- Low power consumption: When the answer mode communication, fast air transmission and start-up time, which greatly reduces the current consumption
- Low application cost: NRF24L01 integrated part of all high-speed signal processing related to RF protocol, such as: automatic retransmission of lost packets and automatically generate response signals, etc.
- NRF24L01 SPI interface: hardware SPI port, MCU I/O ports
- Internal FIFO compatible with a variety of microprocessor interface, micro-controller is convenient
