E33-433T13D is a 20mW wireless transceiver module, which operates at 425-440.5MHz (default: 433MHz), based on originally imported RFIC SX1212 from Switzerland, transparent transmission is available, TTL level. The outstanding advantage of this module is point to point wake-up, which is very suitable for ultra-low power consumption applications.
