Suitable as either a gateway or a node:
Uses enclosure VG-AL53 or Waterproof ABS Enclosure Type VE838 with battery and thermister for stand-alone Lora Node, can be used as Node (battery + I/O for sensors) or gateway with an FTDI/USB serial cable (https://www.aliexpress.com/wholesale?catId=0&initiative_id=&SearchText=VG-AL53) connected to the host computer.
Version 2 with corrected ICSP connectio...
A multipurpose LoRa microcontroller board based on the Atmel 328P microcontroller with an RFM95W LoRa module attached. This version also has an onboard solar power LiPo charger for the integrated 18650 LiPo battery.
Mobile data terminal that runs off 2xAA batteries with 128x128 GLCD, 125Khz EM4100 RFID, BarcodeReader and Lora communications. Based on the new ATMega 4809
Note, this is based on my original PIC16F18857 design which has been working quite well, the only thing that has changed is to replace the microcontroller with the new ATMega4809. The total BOM cost for this board is well under $99 even payin...
