Today we tell you the ingredients you will need in order to reproduce the world’s first IoT sandwich. The sandwich is planned as a starter. We will show you how to make the main course and the dessert later.
Ingredients for the IoT sandwich
For the PCBs
- 9 different PCB shapes (3 different cut-out zones on 3 PCBs = 9 different PCBs)
- 9 GPS chip loop antennas
- 9 U.FL connectors
- 9 capacitors
- 9 inductors
To enclose the PCBs
- 1 plastic enclosure
- 1 LiPo battery
- 1 piece of polystyrene (e.g. Styrofoam)
- 1 piece of German bacon
For the test setup
- 1 Vector Network Analyser (up to 4 GHz)
- 1 U.FL to SMA coaxial cable
- 1 balun inside of the U.FL to SMA coaxial cable
