Review: Does what it's supposed to do (wireless RS-232 bridge) - The need was to get 4800 baud RS-232 data (occasional bursts) from "point A" to "point B" and nothing else - and this did just that. We only needed to go a hundred meters or so and it did that fine. This unit won't run directly from USB (it needs between 6 and 28 volts or so) and it was powered from an existing 12 volt source - and it does NOT come with any antennas, so very small, inexpensive 433 MHz units with female SMA were used: While capable of 1 watt, the power was turned down to 100mW (+20dBm) - the lowest that it would go as the distance was pretty short. It took a bit to find the configuration program online, but it seemed to do the job.

## Features

- E90-DTU(433L30)-V8 is a wireless data transceiver of 433M with standard RS232/RS485 connectors. They are half-duplex. TX & RX modems with LoRa technology and transparent transmission mode. Voltage supply ranges from 8V to 28V, Working frequency: 410~441MHz (Default:433MHz).
- The LoRa direct sequence spread spectrum technology enables the longer communication distance and better power density concentration as well as superior anti-interference ability.
- The FEC algorism enables higher coding efficiency and correction ability. The interfered data packets will be corrected proactively upon sudden interference, which significantly improves reliability and communication distance. Without FEC, the interfered data packet will be dropped.
- The transceivers feature data encryption and compression. The data transmitted in air features randomness, the rigorous algorism makes data interception meaningless.
- The data compression function has possibility to reduce the data transmission time, which in tur reduces the possibility of being interfered, thus improves the reliability and communication efficiency.
