Welcome to place large order! l Introduce RF-TTL-40-TH is our latest 100mW wireless transmission module. It working in 425-450.5MHz band and using serial port to send or receive data. Its advantage is that centralized power density, transmission distance(Its transmission distances can reach 2100 meters.) and strong anti-jamming capability. It can be comparable to most of the 200mW module in current market. RF-TTL-40-SMA having the FEC forward error correction algorithm, the coding efficiency is higher and the error correction capability is strong. When in the case of burst interference, it can take the initiative to correct the interference packets , that greatly improving the reliability and transmission distance. The module also having data encryption and compression function. When transmission data in the air, it is random and unsafe. But after the module rigorous encryption and decryption algorithm, the data interception becomes meaningless and improves transport security. The module has four operating modes , and can freely switch at runtime , in the power saving mo 1.

Module pins and dimensions Pin Num Pin Name Pin Direction Application 1 M0 Input( Very weak pullup) Match with M1, select 4 operating modes of the module. Do not leave 2 M1 Input( Very weak pullup) Match with M0, select 4 operating modes of the module. Do not leave 3 RXD Input TTL serial input and it connected to an external TXD out pin 4 TXD Output TTL serial output and it connected to an external RXD out pin 5 AUX Output Used to indicate the status of the module 6 VDD Power provide, must be between 2.0 to 3.6 DC(Unit: V) 7 GND Ground 1. Module Reset After the module is powered, AUX will immediately output low, begin the hardware self-test and work in accordance with the user parameter settings. In this process, the AUX keep low. After, AUX out high and work in accordance with predetermined operating mode. So users need to wait AUX rising edge, working as a starting point of the module. 2. AUX Detail introduction AUX is used for wireless transmission indication and output indicator. It indicates whether the data has not been emitted by wireless from the module, or the wireless data has been received. 2. Wireless module received data, and it has not completely send to user. All user data have been written to the wireless chip and have started launching. At the same time, the module dose not receive wireless data, and need not output serial data to the user.
