MCU + Load
A microcontroller and its peripherals running from a 5 V rail — the thing everything upstream exists to feed.
- U1 — the MCU.
- C1 / C2 — decoupling (a 100 nF close to the pin + a 10 µF bulk).
Exposes: vdd (5 V, ~1.8 A typ), gnd, and a status signal output.
The
statusoutput is meant to drive an indicator or be read elsewhere — if you leave it unconnected, Electrace will remind you so it isn't silently forgotten.
