Metro RP2350 take 5 🔄🌟🤞

Sometimes mistakes are made in prototyping; that's why they're prototypes. The error in rev D was funny: while making the QFN80 footprint, the pins got placed clockwise rather than widdershins. Not surprisingly, that board didn't come up at all, so here's a full rip-up and reroute, with the correct pinout this time! Fingers crossed. Hopefully, this is the final revision, and we can move on to other RP2350 boards we have cooking.

If your circuit board isn’t working, start by checking for three common problems: poor solder joints, incorrect connections, or power issues. Inspect the PCB for loose or dull solder points, use a multimeter to verify continuity, and confirm that voltage is reaching the right components. Reheat weak joints carefully and fix any wiring errors before powering the board again—this solves most PCB failures quickly.

This approach works because most real-world issues happen during assembly, not design. Engineers, students, and product teams often lose time debugging complex logic when the actual problem is a simple physical fault. A step-by-step check—visual inspection, electrical testing, and controlled rework—helps you identify the issue faster and avoid damaging components.

For better results:

Always test power input first

Check critical connections one section at a time

Avoid overheating sensitive components

Use proper tools for accurate debugging
