What is it?

DIY LoRaWAN Node KIT. It is easy to program by using Arduino IDE. Select board as a Arduino Pro Mini and processor to be 3.3V 8Mhz. Can connect to TTN (www.thethingsnetwork.org) using ABP or OTAA authentication. TTN with Cayenne Integration will allow you easily monitoring your Pro Mini sensor node. Access to our Cayenne Example code Click. What include in this kit is shown on the first picture. The other pictures are for illustrative purposes or building idea only.

Why did you make it?

If you want to learn how lorawan work and would like to make LoRaWAN node by yourselves, you can save your time by using this Kit.

What makes it special?

Easy for you to get started with LoRaWAN technology. You can build a loRaWAN Node with this KIT. Small in size.(63x32mm)

Voltage

!Important! Put the right jumper on FTDI to supply 3.3V (Default from Factory is 5V) Supply 3.3V regulated voltage to 3V3 pin or raw input voltage (4V-12V) to RAW pin.

Remark

Soldering Step 1, you might solder 6 pins female header on the top side of PCB. Don't forget to put the 2P male header inside the Pro Mini area (A4,A5 Pin).

We will send you an Arduino Pro mini ATmega328 (3.3V, 8Mhz) which is a clone product from china.

One 10 cm. long antenna that correspond with your selected freq. (Antenna might look difference from the showed picture.)

For FTDI, make sure you put a right jumper on FTDI. The correct Voltage is 3.3V.

Source Code

You can also generate source code for a few sensors by using the sketch generator Click Here
Select "Continuous sense/Cycled send" After all options are selected, you can click generate. Cut and Paste the program and save as .ino extension. Open sketch file and Change pin mapping to:

.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = LMIC_UNUSED_PIN,
.dio = { 4, 5, 7 },

Arduino IDE Config

Select board Arduino Pro or Arduino ProMini

Select Processor ATmega328 (3.3V, 8Mhz)

LMIC Library There are many LMIC Libraries for Arduino or ATmega MCU Platform. All of them are forked from IBM LMIC (LoraMAC-in-C) library.

Select one of these:

• LMIC 1.51
• LMIC eu868Mhz***
• LMIC New York City us915Mhz
• LMIC India MCCI eu868, as923, in866, us915, au921
• LMIC For AS923 Upper Thailand
• LMIC For AS923 Malaysia MCMC

If you want to use GPS module, you might have the following lines in your sketch:

include SoftwareSerial.h

SoftwareSerial gpsSerial(2, 3)

LoRa Module main Chip is H RF96 or SX1276.
