lets run this all using a usb c. I DO NOT WANT THE POWER RUNNING OFF THE NANO. i also want to be able to interface it incase of code issues, and also i need you to make sure there is lets say to buzzers, i want plenty of sound out of them i want it to function like a RPA system or something the beeps speed up as distance is shorter
Great — I’ll build a Nano carrier powered only from USB‑C, with HC‑SR04, I2C display, two loud buzzers (rate increases as distance decreases), and independent programming/debug.
Plan summary:
USB‑C 5V input with CC pull‑downs, fuse, TVS, bulk/decoupling; feed a 5V rail and isolate the Nano’s 5V (ideal/Schottky diode to prevent backfeed).
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
