LoRa1284 is an Arduino compatible board using an ATmega1284P. It has provision for an onboard LoRa wireless module making it suitable for remote sensing and control.
For a while now I have been making projects using wireless comms for remote sensing and control. In particular I have been using LoRa modules for their reliability and long range operation.
For many projects an ATmega328 is more than adequate but once you start adding libraries for LoRa, OLEDs, etc memory and I/O pins start to run out. This is where the ATmega1284 comes in. Not only does it have extra flash, SRAM, EEPROM and I/O pins but existing Arduino libraries just work!!!
Each LoRa1284 comes in an anti-static bag that includes:
How to program?
You need to add board support in the Arduino IDE.
Go to https://github.com/mcudude/MightyCore and follow the "Boards Manager Installion" link.
For convenience the following is copied from the MightyCore link:
Boards Manager Installation
This installation method requires Arduino IDE version 1.6.4 or greater.
Powering the LoRa1284 module
There are two options for powering the LoRa1284 board - via VIN or via the 3V3 pins.
Powering via VIN
Powering via 3V3 pins
Why would you want to? For running on batteries such as LI-ION or LI-PO. However there are limitations as described below.
The 3V3 pins are direct connected to the ATmega1284 Vcc pins and that is the operating voltage range of the ATmega1284 chip itself
Low power operation
For low power operation the onboard power and blink LEDs can be disabled by removing solder jumpers SJ1 and SJ2
