Fits in type 6063-T5 aluminum junction boxes 71*25*85mm
PIC Firmware (as a complete MPLABX Project) attached for a basic transparent gateway function.
Only 300 lines with no dependent libraries so Easy to understand and modify to your favourite CPU as required.
Mostly one layered project (except one wire) with Arduino pro mini 3v3 board and LoRa RA-2 module. Soldering the shorter header 1x6 strongly optional, in that case you have to solder the LoRa 3v3 pin to Arduino regulated 3v3 VCC.
PCB V1.1 has no 1x6 header.
**Be careful** with the PCB, because the LoRa module has been flipped and the nets do not renamed. It is ideal for home etching with (not?)...
This is a LoRa node, powered by the ESP32 WROVER-B microcontroller. ESP32-WROVER-B is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding. ESP32-WROVER-B features a 4 MB external SPI flash and an additional 8 MB SPI Pseudo static RAM (PSRA...
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.
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...
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...
