NRF24L01+ upgrade wireless module SI24R1 wireless transceiver module 2.4G Ball open ISM band maximum 0dBm transmit power, license-exempt use. Open 100 meters! It supports six-way data channel reception features 1. The low operating voltage: 1.9 ~ 3.6V low voltage operation 2. The high rate: 2Mbps, because the air transport time is very short, greatly reduced the wireless transmission of collision phenomenon (software settings 1Mbps or 2Mbps air transmission rate) 3. Multi-frequency: 125 frequency, multi-point communication and frequency hopping to meet the communication needs 4. Ultra-small: Built-in 2.4GHz antenna, small size, 15x29mm (including antenna) 5. Low power consumption: When working in answer mode communication, fast air transport and start time, greatly reduce the current consumption. 6. Low application costs: NRF24L01 integrates all RF protocols related to high-speed signal processing section, such as: automatic retransmission of lost packets and automatically generate response signals, NRF24L01 SPI interface can be used to connect the microcontroller hardware SPI port or using SCM I / O port to simulate internal FIFO can be used with a variety of high and low speed microprocessor interface, easy to use low-cost microcontroller. 7. facilitate the development: Due to the link layer is fully integrated in the module is very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost packets, the retransmission time and the number of retransmissions can control software automatic storage not received response signal packets auto-answer, after receiving valid data, the module automatically sends a response signal without any additional programming carrier detect - fixed frequency detection built-in hardware CRC error detection and multipoint communication address control packet transmission error counter and carrier detection function can be used to set the frequency hopping can also set the six-way receive channel address, selective open receiving channel standard pin Dip2.54MM pitch interfaces for embedded applications
