[Introduction]：E330-400T13S is a small size, low power consumption, low cost, ultra-high cost-effective serial port module, integrated transceiver, covering 433MHz and 470MHz frequency bands.
[Introduction]：E330-900T13S is a small size, low power consumption, low-cost ultra-high cost-effective wireless serial port module, integrated transceiver, covering 868, 900MHz frequency band. The wireless module supports transparent transmission, fixed-point transmission mode, supports LDC single-point wake-up, software multi-level airspeed adjustable, and can be applied to a variety of wireless transmission applications. At the same time, the module is simple and easy to use, and you can get started quickly without complicated configuration, so that it can be used out of the box.
