A great little solution for wireless control that allows up to 2Mbit communication over the range of 40-100m. It has an antenna. The nRF24L01 is a single-chip 2.4GHz transceiver with a built-in baseband protocol engine (EnhancedShockBurst ™) designed for ultra-low power wireless applications.
The
nRF24L01 is designed to operate in the global ISM frequency band of 2.4002.4835GHz. Designing a wireless system using the nRF24L01 requires an MCU (microcontroller) and a few external passive components. The nRF24L01 is configured and operated via the Serial Peripheral Interface (SPI). Register mapping is available from this interface. The register map contains all the configuration registers of the nRF24L01 and is accessible in all modes of operation of the chip.
The
Embedded Baseband Protocol Engine (EnhancedShockBurst ™) is based on packet communication and supports a variety of modes, from manual operation to enhanced autonomous protocol operation. The internal FIFO ensures a smooth flow of data between the wireless front end and the system's MCU. Enhanced ShockBurst ™ reduces system costs by handling all high-speed link-layer operations. The wireless front end uses GFSK modulation. There are user-configurable parameters such as frequency channel, output power, and air data rate.
Features of NRF24L01 2.4GHz Wireless Transceiver Module:
- 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
