B01HYO608A Price: $19.95 Score: 6.623 Category: Electronics Rating: 4.3 Votes: 34 Find similar products Adafruit (PID 3072 RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz. Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren't so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can't send data as fast but you can send data a lot farther.' The modules do packetization, error correction and can also auto-retransmit so its not like you have worry about everything but less power is wasted on maintaining a link or pairing. These modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node nework or transmit data over a campus or town. The trade off is you need two or more radios, with matching frequencies. This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweaking Range of approx. 2Km, depending on obstructions, frequency, antenna and power output All radios are sold individually and can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz, LoRa 433 MHz can only talk to LoRa 433, etc. Each radio comes with some header, a 3.3V voltage regulator and levelshifter that can handle 3-5V DC power and logic so you can use it with 3V or 5V devices. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Optionally you can pick up a uFL or SMA edge-mount connector and attach an external duck.

Low-Cost Software Defined Radio Compatible with Many SDR Software Packages. R820T Tuner & ESD-Safe Antenna Input. The perfect device for learning software defined radio, on the cheap. Amateur radio, ADS-B, police & fire scanning, trunking, satellite images--you name it, this little guy can probably do it. Outperforms many devices 10x its cost! These units are based on the R820T tuner IC made by Rafael Micro. As such, they have a frequency capability of approximately 27MHz-1700MHz, though this can vary somewhat from unit to unit. There is also an RTL2832U IC on board of course, which acts as the demodulator and USB interface. The connector type on the antenna and USB board is MCX--male MCX on the antenna, female MCX on the SDR. We perform extensive QA on every batch sold. As with all our SDRs, we guarantee antenna protection will be present so that your new investment will not be quickly destroyed by spurious ESD. SOFTWARE DETAILS Full compatibility with a large array of software packages, such as MATLAB, HDSDR, SDR Touch, SDR#, Planeplotter--too many to list. MathWorks and Nooelec have coordinated to bring MATLAB support for our SDR receivers. The RTL-SDR radio support package enables you to design wireless receivers using real world signals. Using Communications System Toolbox in conjunction with an RTL-SDR USB radio, you can design and prototype systems that process real-time wireless signals in MATLAB and Simulink.

B09R6JV4TJ Price: $299.95 Score: 6.024 Category: Electronics Rating: 3.2 Votes: 2 Find similar products SparkFun GNSS Timing Breakout-ZED-F9T (Qwiic)-Compatible w/Arduino Multi-Band GNSS Receiver-Up to 5 nanosecond Timing Accuracy w/a Standard Position Lock-GPS GLONASS Galileo & BeiDou Constellations. The SparkFun GNSS Timing Breakout offers a unique entry into SparkFun's geospatial catalog featuring the ZED-F9T GNSS receiver from u-blox. The ZED-F9T provides up to five nanosecond timing accuracy under clear skies with no external GNSS correction making it perfect for applications where timing accuracy is imperative. Need an extremely accurate time reference to maximize the efficiency of your IoT network of 5G devices? The ZED-F9T GNSS Timing Breakout could be the perfect solution. The ZED-F9T is a multi-band GNSS module that supports L1/L2/E5b bands and operates on all major constellations (GPS, GLONASS, Galileo and BeiDou) concurrently making it extremely versatile and able to retain its timing precision even the module loses lock with one or more of the visible constellations. This breakout shares a similar design as the SparkFun GPS-RTK-SMA Breakout to create a small but comprehensive development tool for the ZED-F9T. The design includes a USB-C connector for primary power and communication, two Qwiic connectors for communicating over I2C using the SparkFun Qwiic system, three SMA connectors for the antenna and timing pulse signals as well as a host of PTH pins allowing direct interaction with most of the ZED-F9T's pinout. The GNSS Timing Breakout also includes an on-board rechargeable backup battery that provides power to the RTC on the ZED-F9T. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
