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. | ![]() B00X0J8WBM Availability: Currently unavailable Score: 6.098 Category: Electronics Rating: 5 Votes: 1 Find similar productsSparkFun BLE Mate 2. This is the SparkFun BLE Mate 2, an efficient and reliable Bluetooth 4.0 development board. The BLE Mate 2 closely resembles a breakout board, in that nearly every pin on the on-board BC118 module is made available to access. This board is actually a close cousin to our Gold and Silver Bluetooth Mates and functions in a very similar way but, as the name implies, operates as Bluetooth Low Energy instead of Bluetooth 2.0. The BLE Mate 2 offers a six-pin header on the end opposite the BC118 module which is used as a “host” serial pinout, the same as that on the FTDI Basic boards, which allows the BLE Mate 2 to be connected directly to any device with a matching header, such as the SparkFun Arduino Pro and Pro Mini. Coupled with the FTDI SmartBasic, you can even develop your code without having to swap cables! The board has built-in level translation, so it can be used with boards of higher voltage than the 3.3V default used by the BC118. Each BLE Mate 2 offers BC118 module that is capable of accepting and transmitting via the UART at 9600bps (default) with a frequency band of 2,402 MHz to 2,480 MHz. The SparkFun BLE Mate 2 only supports Bluetooth 4.0; it won’t connect to older devices. It’s also worth noting that BLE does not support a Serial Port Protocol as older versions of Bluetooth did; that makes interoperability between BLE dongles, devices, and modules harder than with Bluetooth Classic. |

The PL-2303HX is a low cost and high performance USB-to-Serial Bridge Controller. The PL-2303HX provides a convenient solution for connecting an RS-232 like full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL-2303HX highly compatible drivers could simulate the traditional COM port on most operating systems allowing the existing applications based on COM port to easily migrate and be made USB ready. The PL-2303HX is exclusively designed for mobile and embedded solutions in mind, providing a small footprint that could easily fit in to any connectors and handheld devices. With very small power consumption in either operating or suspend mode, the PL-2303HX is perfect for bus powered operation with plenty of power left for the attached devices. Flexible signal level requirement on the RS-232 like serial port side also allows the PL-2303HX to connect directly to 5V, 3.3V, or 2.5V devices. Works well with Linux and Mac. Does not work so well with Windows. If you are running Windows then buy a FTDI FT232RL board instead. | ![]() B073WWKWY3 Price: $35.94 Score: 6.061 Category: Electronics Rating: 4 Votes: 12 Find similar productsColorlight 5A-75B Receiving Card Led Display Synchronous Control Card(V8.0 Version) with Software Configuration Instruction.
