Tasks accomplished:

1. Made a schematic.
2. Made an enclosure for the Radio.

The radio is supposed to powered by the phone and use the phones microphone and speaker as the interface, the goal is to practically compare ESP-NOW communication protocol and the 2.4ghz transceiver module and adaptively transition or switch to either protocol but there is a caveat, they communicate at the same frequency band and can interfere but we can only test it to know more
