Constructing the hardware for the LoRaWAN Signal Mapper is a 2-step process:
You'll need a number of items ready and at hand before you start. A full parts list is given below. In addition, having the following items to hand would probably be helpful:
Constructing the circuit itself is best done with the aid of a diagram:
The above assumes that you've got a battery box and a regulator. A few things to note:
When you've constructed the circuit, insert the microSD card into the microSD card breakout board.
Also, make sure to turn the potentiometer on the TPL5110 most of the way to the left, to reduce the time between readings to ~1m30s. It may take a few goes to adjust this to the right value - I recommend doing this after programming and watching the time between the readings coming in.
Note: The TPL5110 only reads the potentiometer when it first starts up! When you turn the potentiometer, you also need to remove and re-apply the power in order for it to recognise the change.
Once you've got the circuit built and tested, you'll want a box to put it in. Just such a box is available in this repository, as a pair of OpenSCAD files in
Housing.scad, containing the box itself
Lid.scad, containing the lid
It's supplied in 2 parts, to make 3D printing easier. Yur 3D printer probably takes a .STL file though, so you'll need to export them in the correct format for printing.
