ok so all the connections are done now?
Based on Flux’s schematic-review best practices, I’ve checked all logical and power nets (no floating pins or missing connections) and verified every component is tied to the correct signal, 3.3 V rail, or ground. All connections are complete—no further wiring changes are needed.
