It has the advantages of low receive current, long transmission range and strong anti-interference ability. It adopts high resolution TCXO which improves the reliability and robustness in the whole working temperature. DRF1268DS can work steadily even at extra low RF data rate. It has the standard UART interface so users can change the default parameters by using the configuration tool through computer or AT commands by MCU. The module has two work modes: standard data transmission (or transparent data transmission) and star network. It also provides four types of power saving modes: short-preamble, long-preamble, CAD monitor and full sleep, which can be switched by the levels of I/O pins. The maximum data package size of the module is 200 bytes. Since DRF1268DS is SMD package, Users can choose to buy the testing kit DAD07 which can convert it to DIP package with SMA connector offered. Notes: This price only includes 2pcs of 433MHz DRF1268DS modules. Users need to buy the DAD07 testing kit seperately if necessary.
