[Introduction]：E33-433T13D is embedded in a high-speed low-power microcontroller and a high-performance chip SX1212. The transmission power is 20mW, and only 3.0mA is consumed in the receiving state. It has a single point wireless wake up function (only the waking object is specified, and all receivers do not need to exit the sleep mode). Single point wake up is a very important indicator, which can greatly save system power consumption.
