Innoesys LoRa Shield is an Arduino shield for Low-Power Wide-Area Networks (LPWAN) designed for long range communications with low bitrate. *** Long range: greater than 15 km *** Applications: Internet of Things Sensor networks Agriculture applications Industrial automation Smart city Smart meters Home automation Manufacturer: Innoesys (www.innoesys.com)...
The 868/915MHz antenna needs to be in connection with the IPEX interface (if the antenna is not connected, it may damage the LoRa chip). When using, pay attention to the positive and negative of the battery, otherwise it will be damaged!With IO port touch screen touch signal input, you need to add the 100nF pull-down capacitor to this pin!
The LoRa/GPS Shield is an expension board for LoRa™/GPS for using with the Arduino.This product is intended for those interested in developing LoRa™/GPS solutions.The LoRa/GPS Shield is composed of LoRa/GPS Shield mother board and LoRa BEE.
