KTC CONS LABS NRF24L01 SMD Wireless Transceiver + 2.4GHz Antenna Module for Microcontroller Radio Electronic Hobby Kit

ISM single-chip transceiver, wireless transceiver, including: frequency generator improved schokbursttm mode regulator power amplifier crystal amplifier modulator demodulator Power output channel selection and protocol set by SPI interface for installation very low current consumption, lower current consumption mode 12.3mA power off mode and standby mode, when transmitting power is 6dBm, when current consumption is 9.0mA receiving model. Ball for opening ISM band maximum transmit power 0 dBm, use without license. Open 100 meters! Supports six channels of data reception (1) low working voltage: 1.9 ~ 3.6V low voltage (2) high speed: 2Mbps, the air transmission time is very short, which greatly reduces the wireless collision transmission rate (software settings 1Mbps or 2Mbps air transmission rate) (3) Multi-frequency points: 125 frequency points, to meet the needs of multi-point communications and frequency hopping (4) ultra-compact: built-in 2.4GHz antenna compact 15x29mm (including antenna) (5) Low power consumption: When communicating in answer mode, the fast air transfer and start-up time greatly reduce the current consumption. Low cost of application: NRF24L01 integrates all high-speed RF signal processing protocols, such as: automatically re-process lost packets and automatically generate a validated signal, etc. nRF24L01 SPI interface can use microcontroller's hardware SPI port or microcontroller I / O port to simulate internal FIFO can be used with a variety of low-speed microprocessor interface, easy-to-use low-cost microcontroller. Ease development: The connection layer is fully integrated into the module, very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost packets, retransmission time and retransmission amount can be programmed, automatic storage is not received auto-reply response signal packet, after receiving valid data, the module will automatically send a response to signals with a fixed frequency without any additional carrier software detects Built-in hardware CRC Error detection and point-to-multipoint packet transmission address control error counter and carrier detection Used for frequency hopping set, can also set six to get the channel address, can have the choice of open pin receiving channel dip2.
