I am a software guy, with very little hardware experience.
I am excited by BLE 5.1 and its location & distance functionality, using AoD & AoA.
My first thought it to have two devices, each with a display, and have them each display an arrow and a distance to the other, updating as the devices move. I have a few contacts would would be much more excited by this simple demo in their hands than by any amount of explanation from me. Just looking at such a thing, I am sure that they can take their domain knowledge and come up with several ideas for potentially marketable products.
Given my lack of hardware experience, can anyone suggest a battery powered dev board which I can use? No soldering, please, although plug & play is acceptable if the board does not have an on-board display (I am thinking HAT/shield).
Thanks in advance for any suggestions.
