Description
The LR900-F is a new long-range telemetry radio developed by MicoAir Technology based on LoRa spread spectrum technology. It operates in the 890-915MHz frequency band with a maximum transmission power of 500mW and supports FHSS self-interference hopping mode. With the outdoor RF line-of-sight range of 30km or more, it can provide a reliable point-to-point bidirectional communication link for drones, ships, robots, and RTK devices.
It has two ports: one is a TTL serial port, which can be directly connected to flight controllers and other devices, and the other is a Type-C USB port, which can be connected to a computer or an Android phone.
In default duplex mode, it only requires the two address parameters to be consistent for direct interconnection communication, which greatly facilitates the installation and use.
Features
- Works in 915MHz (890-915MHz)
- Small size and light weight (8g)
- Transmit power up to 27dBm (500mW)
- Base on LoRa modulation technology to obtain excellent anti-interference performance
- On-board SAW filtering
- Using transparent transmission to compatible with any data and protocol not just mavlink
- On-board dual interfaces CP2102 USB to UART IC, compatible with QGroundControl on Android
- Diversity antenna support

Great long range telemetry and serial link

Buy the mainstream brands for this half-baked telemetry stuff. There are no support options, there is an "application" to download and to set it up but there is zero instructions and none of the options can be selected. The app barely works other then to send TEXT out the comport at regular intervals.No settings can be tailored. Example: App Defaults to 115K Baud but the devices are cofigured somehow to 57K out of the box. App can't even read the device to identify it as its own brand.No way to "bind" these. Looks hard coded for binding with the same unit. The app is just a COM tool with buttons that don't work.No Firmware updates, No manuals, No settings or config options, No pinouts (The Amazon Order Item info is about it for details).

These modules worked exactly as they were expected to work. I was able to download the configuration app and make changes. They find each other immediately and work as if the serial port was directly connected to the computer.
