{"product_id":"pl4-wrl-15836","title":"Pro RF - LoRa, 915MHz (SAMD21)","description":"\u003cp\u003eThe SparkFun Pro RF is a LoRa®-enabled wireless board that marries a SAMD21 and a long-range RFM95W to make a compact and easy-to-use IoT Arduino board. With its fast MCU and excellent point to point data transmission in the 915MHz ISM band with LoRa Capabilities, the Pro RF is a great choice for anyone interested or experienced in utilizing long range data communication.\u003c\/p\u003e \n\n\u003cp\u003eEvery pin on the SparkFun Pro RF is accompanied with a ground connection making the buttons and LEDs easy to connect. In case you're building something to be embedded into clothing or other physically harsh environment the antenna includes a stress relief hole to make sure your wire antenna survives. A short (3 inch) wire antenna is sufficient for \"short\" distances (up to 1 mile line-of-sight), but we've also included a u.FL antennae connector for potentially longer distances.\u003c\/p\u003e\n\n\u003cp\u003eThe Pro RF also includes a power switch and 2-pin JST connector for powering from a lithium battery. With a Micro-B USB and the power switch in the off position, the Pro RF will charge the attached battery! The board programs over a reinforced Micro-B connector with a slim reset button that fits nicely on the side of the board. Weve even added our popular [Qwiic](https:\/\/www.sparkfun.com\/qwiic) connector to the edge of the board making it incredibly easy to add sensors and actuators without the need for solder or a soldering iron!\u003c\/p\u003e\n\n\u003cp\u003eThanks to the Arduino LoRa library, the RFM95W radio is an easy to use packet radio. But it doesnt stop there because closing a few jumpers on the underside of the SAMD21 Pro RF initiates LoRaWAN mode on the radio module making it a node in a distributed sensor network.\u003c\/p\u003e \n\n\u003cp\u003e-\u0026gt;\u003c\/p\u003e","brand":"SparkFun","offers":[{"title":"Default Title","offer_id":39690193174709,"sku":"PL4-WRL-15836","price":65.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/15836-SparkFun_Pro_RF_-_LoRa__915MHz__SAMD21_-01.jpg?v=1618122519","url":"https:\/\/getcahits.com\/zh\/products\/pl4-wrl-15836","provider":"PuriLite","version":"1.0","type":"link"}
