Package Included:
1*wireless data transmission module
Specifications:
Name: Micro 2.4G Wireless Module
Model: 24L01-M
Power supply voltage: 1.9~3.6V
The receiving sensitivity is 2Mbps. -83dB; 1Mbps ●-87dB; 250kbps . -96dB
The receiving current is 2Mbps-15mA; 1Mbps-14.5mA; 250kbps - 14mA
Standby current: 15μ A
Power-down current: 700nA
Operating temperature: -20C ~ +55C
Storage temperature:-40 C ~+125 m
Description:
NRF24L01 is a monolithic transceiver chip working in the ISM frequency band of 2.4-2.5GHz. The wireless transceiver includes: frequency generator enhanced SchockBurstTM mode controller power amplifier crystal amplifier modulator demodulator output power channel selection and protocol setting can be set through SPI interface. The current consumption is 9.0mA when the transmission power is 6dBm in the transmission mode, 12.3mA in the acceptance mode and lower in the standby mode.
The ISM frequency band is open, which has a large transmission power of 0dBm and is free of license. Support six channels of data reception.
1. Low working voltage: 1.9～3.6V low voltage operation
2. High speed: 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)
3. Multi-frequency point: 125 frequency points, meeting the needs of multi-point communication and frequency hopping communication
4. Ultra-small: built-in 2.4GHz antenna, small size, 15x29mm (including antenna)
5. Low power consumption: when working in response mode, the fast air transmission and startup time greatly reduce the current consumption.
6. Low application cost: NRF24L01 integrates all the 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 by hardware SPI port of single chip microcomputer or simulated by I/O port of single chip microcomputer. The internal FIFO can interface with various high and low speed microprocessors, which is convenient for using low-cost single chip microcomputer.
7. Easy to develop: Because the link layer is completely integrated on the module, it is very convenient to develop. Automatic retransmission function, automatic detection and retransmission of 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.
