[Introduction]：E95-DTU (433C20-485)-V2 is a data transmission station of the continuous transmission 433M wireless data transmission module, with built-in high-performance microcontroller and wireless transceiver chip. Works in the 410-441MHz frequency band (default 433MHz), with a transmit power of 20dBm. The main function is that when the module is in continuous transmission mode, it can perform continuous and uninterrupted transmission at different serial port baud rates, and the data output delay at the receiving end is low, which is suitable for scenarios where large amounts of data need to be transmitted quickly.
