1sets GT-24 Special promotions 1100-meter long-distance NRF24L01+PA+LNA wireless modules NRF24L01 NRF24L01 is a single chip transceiver chip operating in the 2.4-2.5GHz universal ISM band, wireless transceivers include: Frequency generator Enhanced SchockBurstTM Mode Controller Power Amplifier Crystal Amplifier Modulator Demodulator Output power channel selection and protocol Settings can be set via SPI interface with very low current consumption. The current consumption is 9.0mA when the transmission power is 6dBm in transmit mode, 12.3mA in receive mode, and the current consumption mode is lower in standby mode. Ball open ISM band, 0dBm transmit power, license free use. Supports six channels of data reception ? 1. Low operating voltage: 1.9 ~ 3.6V Low voltage operation ? 2. High speed: 2Mbps, due to the short air transmission time, greatly reduce the collision phenomenon in wireless transmission (software set 1Mbps or 2Mbps air transmission rate) ? 3. Multi-frequency: 125 frequency points to meet 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 communication, fast air transmission and startup time greatly reduce current consumption. ? 6. Low application cost: NRF24L01 integrates all high-speed signal processing parts related to RF protocol, such as: The SPI interface of NRF24L01 can be connected by the hardware SPI port of the single chip microcomputer or simulated by the I/O port of the single chip microcomputer. The internal FIFO can be used to interface with various high and low speed microprocessors, which is easy to use the low-cost single chip microcomputer. ? 7. Easy to develop: Because the link layer is fully integrated on the module, it is very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost data packets, retransmission time and retransmission times can be controlled by software to automatically store the data packet automatic response function that does not receive the response signal. After receiving valid data, the module automatically sends the response signal. No need to program carrier detection - fixed frequency detection Built-in hardware CRC error detection and point-to-multipoint communication address control packet transmission error counter and carrier detection function can be used for frequency hop setting can be set at the same time six receiving channel addresses, can selectively open the receiving channel standard pin Dip2.54MM pitch interface, easy to embedded applications. ? ? _x000D_ _x000D_
