This module applies to any wireless data transmission application with complex environments, such as wireless meter reading, smart home control, automotive electronics, security alarm, industrial monitoring, and control system, remote agricultural irrigation control system, etc. The module can be easily embedded into the design of customers' existing products or systems. The standard SPI interface makes communication easy. Customers only need to compile a simple communication protocol in the original micro-control device to realize two-way communication and data transmission. The wireless module receives data through the NIRQ port to notify the single-chip computer to receive, and the single-chip computer reads the data received by the wireless module through the SPI interface. Based on the SPI interface mode, it is very convenient for various MCU connections. It can do all kinds of wireless and two-way data receiving and sending. The single-chip computer controls the wireless module to transmit, receive data or sleep through SPI. XL1276-P01 uses the spread spectrum chip sx1276, which has the advantages of low power consumption, large capacity, long transmission distance, and strong anti-interference ability. The transmission power, working frequency, modulation rate, and other parameters of the module can be configured by the single-chip computer.
