E70-433NW14S star network module LoRa spread spectrum technology wireless transmission monitoring
[Introduction]：E70-433NW14S is the star network module, operating at 433MHz, based on originally imported TI CC1310 and 15.4-Stack protocol, with coordinator and terminal as a whole. The module features with long range and high-speed transmission modes. Maximum 200 nodes can send data to one coordinator.
