This board is the core of a LoRa based energy monitor which can be used to monitor the load on Distribution Transformers, Electricity Generators or Electricity Feeders in real-time. The design was inspired by the [Open Energy Monitor Project](https://openenergymonitor.org/). The board can connect to a LoRa gateway up to 15KM away making it possible to monitor a large network of distribution transformers easily. Together with an ADC conditioning board which is connected to the group of pins labeled J2, the load on the three phases of an energy source can be read into the system and transmitted over a LoRa Network to a datacenter for analysis and visualization. This board has an ATMEGA328 processor on board and is powered by a LiPo battery which can be recharged using the a 6V solar panel. This design has the following features: 1. 5dB PCB antenna for 868MHz 2. CN3065 Solar LiPo Charger 3. Onboard GPS using the Quectel L80-R GPS module. 4. Battery and Solar voltage monitoring using the ADS1115 Analog to Digital converter. 5. LoRa communication module RFM95W This board has dedicated 6 pin interface for the ADC input conditioning daughter board. This design exposes all available digital I/O and analog-to-digital I/O not connected to onboard hardware. The following I/O lines are dedicated to hardware: 1. GPS module - pins D8 (GPS ++EN++), D9 (TX) & D10 (RX). 2. LoRa Module - pins D2 (DIO0), D3 (DIO1), D4 (DIO2), D5 (RST), D6 (NSS), D11 (MOSI), D12 (MISO), D13 (SCK) 3. Voltage Monitor - A4 (SDA), A5 (SCL) 4. LED - D7 The following I/O PINS are labeled but may also be used for any other input output function. 1. Ultrasonic Sensor (D14/ECH, D15/TRG). 2. ADC Conditioning Daughter Board (A2, A3, A6, A7) Full documentation including sketch samples and integration to a back-end will be available on my github page shortly.
