K62-DL20 Ebyte OEM/ODM cheap 4000m RS485/LoRa Wireless Spread Spectrum Point-to-point 4-20mA analog transmission module
[Introduction]：Features: This product is a product with two functions. Function: The sender collects 4-channel analog signals (0/4～20mA) and transmits the data to the receiver through wireless (LoRa spread spectrum), and the receiver restores the 4-channel analog signal (0/4～20mA).
