TTN Node

TTN Node IoT.jpg

Build your own TTN Node / IoT Sensor in one afternoon. Some soldering and programming required.

This TTN Node exist of the folowing components (Cost € 25,=) :

  • Arduino nano (clone)
  • Microchip RN2483
  • Print
  • Battery
  • USB kabel

If you join this workshop you get all of the above parts to make the Node. You are also welcome if you have your own parts and want a own TTN design, we can then exchange experience and tips.

Join this workshop here.


Instructions

Test Arduino Nano - Program blink, change frequency, blink.

  • Software serial on pins 10, 11. Add wire for loopback.

Solder RN2483 - Press down with finger at correct location. Tin on corners.

Break header strip into two peices of 15 pins.

  • Use spreader to hold right angle header strips in place.
  • Solder first and last pin of header strips.*
  • Remove spacer, solder rest of header pins.

Press Arduino Nano down on soldered header strips.

  • If everything looks correct, solder the Arduino to the header pins.

TTNCTL

Arduino code - https://github.com/jpmeijers/ttnmapperarduino

  • Download the zip file and place the library and example files in your Arduino folder.
  • Open TXfastViaTTN.ino
  • Change line 74 to your own AppEUI, NwkSKey, AppSKey and DevAddr
  • Program the code to the Arduino.
  • If everything is correct you should see packets arriving in ttnctl.

Optional

  • Install the TTNmapper Android app and help us map the coverage of the network.
  • Read the internal temperature sensor of the Arduino and transmit the value over TTN.
  • Add an external prototyping board, add sensors, transmit the values.
