ماژول +NRF24L01 - برد SMD

Six channels supporting data reception
1. 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
The ultra-small: Built 2.4GHz antenna, compact, 15x 29 mm (including antenna)
5. Low power consumption: When operating in answer mode communication, fast air transport and start-up time, which greatly reduces the current consumption.
6. Low application costs: NRF24L01  integrates all RF protocols related to the high-speed signal processing section, such as: automatic retransmission of lost data packets and automatically generates response signals, NRF24L01 of SPI interfaces can use microcontroller hardware SPI mouth connection or with MCU I / O port for simulation, internal FIF O can be used with a variety of high and low speed microprocessor interface, easy to use low-cost microcontroller.
7. facilitate the development: Since the link layer is fully integrated in the module is very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost packets retransmission time and the number of retransmissions can be software-controlled  automatic storage not received response signal packets automatic answer function, after receiving valid data, the module automatically sends a response signal, without further 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 be set at the same time six-way receive channel address, selective open receiving channel standard pin Dip2.54MM pitch interfaces for embedded applications.
