needs doxygen docu - derived from ThroughLoRa/DeviceGeneric, Uno_Dragino_LoRa_GPS_Shield_TTN and https://github.com/Play-Zone/BME280_MAX44009/blob/master/example.ino also derived from https://www.arduinolibraries.info/libraries/bme280 and https://www.arduinolibraries.info/libraries/i2-c-sensor-lib-i-lib ...
Arduino Uno (5V): use it with dragino lora gps shield (set ENABLE_GPS) or with lorabee only (do not set ENABLE_GPS) weatherstation breakout is always needed consider using hardware serial for gps (if gps used in OWPJON device)
Arduino Mini 3.3V: It is a minial atmega328 w. 8MHz oscil. so a procedure similar to "Using on (minimal/raw) atmega328 w. 16MHz oscil." as mentioned in

- OWPJON/ARDUINO/Local/SoftwareBitBang/OWP_DG_1w-adaptor/OWP_DG_1w-adaptor.ino works here also (this uses 5V so board needs to be taken out of 3.3V circuit!): use Uno with ArduinoISP Example and "Arduino as ISP" connect (like attiny85) for ISP (SPI) programming (13-13, 12-12, 11-11, 10-RESET, 5V-VCC, GND-GND - 5V also for 3.3V boards possible!) see e.g. https://www.arduino.cc/en/tutorial/arduinoISP https://www.arduino.cc/en/Hacking/MiniBootloader http://www.gammon.com.au/breadboard https://github.com/nickgammon/arduino_sketches (for debugging see "Chip not detected", "Alternate clock source") select "Arduino Pro or Pro Mini" board, select the correct "Procesor" (depending on voltage on clock) and Tools > Burn Bootloader then compile and upload sketch with (Upload button doesn't work) Sketch > Upload Using Programmer (selecting othe 328 board like Uno or Nano would work also but not allow to select 8MHz clock) info on (RobotDyn) Arduino (Pro) Mini (3.3V): https://learn.sparkfun.com/tutorials/using-the-arduino-pro-mini-33v/all https://robotdyn.com/catalog/promini-atmega328p.html pinout: https://robotdyn.com/pub/media/0G-00006155==ProMINI-ATmega328P(10PCS)-USBCH340-KIT/DOCS/PINOUT==0G-00004034==ProMINI-ATmega328P.pdf schematic: https://robotdyn.com/pub/media/0G-00006155==ProMINI-ATmega328P(10PCS)-USBCH340-KIT/DOCS/Schematic==0G-00004034==ProMINI-ATmega328P.pdf
For a plain 3.3V operation we can use a Due: use Due with ArduinoISP Example and "Arduino as ISP" uncomment '#define USE_OLD_STYLE_WIRING' (line 81) in order to use same wiring as mentioned before (using the SPI/ICSP header does not work (yet)) for programming the Due with ArduinoISP use the "Programming Port" (USB connector in middle of board) for programming the target (Arduino Mini) and use as "Arduino as ISP", use the "Native Port" (USB connector at the edge of the board) https://petervanhoyweghen.wordpress.com/2015/07/21/arduinoisp-reliability-and-portability-improvements/ in case of issues reset the Due by pressing the button and re-select USB port in case Burn Bootloader fails check enable verbose output (Preferences) and check it, sometimes it tries to burn twice and only 2nd time fails (ignore it) select "Arduino Pro or Pro Mini" board etc. as mentioned before
Upload using bootloader with Due RX/TX as mentioned in

Direct Pinout (not using shields, e.g. for Arduino Mini 3.3V): Arduino Mini 3.3V Peripherial VCC supply: 3.3V VCC LoRa Bee: 1 (3.3V) VCC Weather St.: VCC GND supply: GND GND LoRa Bee: 10 (GND) GND Weather St.: GND 9 LoRa Bee: 5 (RESET) - SPI 10 LoRa Bee: 17 (CS/NSS) 11 LoRa Bee: 11 (DI/MOSI) - SPI 12 LoRa Bee: 4 (DO/MISO) - SPI 13 LoRa Bee: 18 (CLK/SCK) - SPI A4 Weather St.: SDA - I2C A5 Weather St.: SCL - I2C optional: RAW supply: 5V (+2.5V...+16V) (optionally replaces 3.3V supply e.g. by 5V or 3.7V LiPo, Lora Bee and Weather St. still need to be connected to VCC, VCC then gives max. 180 mA!)
