【Features】
[] USB to nRF24L01+ module realizes the communication from SPI interface of 2.4G wireless module to TTL serial port and then from USB to TTL serial port chip to USB interface. That is, USB interface 2.4G wireless module =2.4G wireless module SPI interface +STM32 microcontroller +USB to serial chip CH340. Customers don't need to know the communication protocol of the 2.4G wireless module in detail, but only need to know how to use the serial port to operate. They can configure the wireless communication parameters through several AT instructions of the serial port assistant, and the system parameter settings will not be lost when power is off, and will remain in the last state after power is on. Built-in watchdog anti-crash program can run stably in industrial control situations with harsh environment. Shorten the research and development cycle, and facilitate the rapid verification and testing of the wireless communication system designed by ourselves. Using RFX2401C RF front-end amplifier chip, the wireless signal can be amplified to a maximum of 22dBm, effectively increasing the communication distance of the signal.
