Checking Binary Watch Schematic Audit progress…
"Binary Watch Schematic Audit" completed.
Thought for 17 sec
The repair pass is complete. I’m independently checking the updated ERC results and the critical MCU, clock, button, LED, and programming nets now.
Worked for 35 sec
Schematic issues fixed: added NRST filtering, three button pull-ups, corrected LSE capacitors to 8.2 pF, and marked unused MCU/header pins no-connect. Fresh ERC and passive checks are clean.
Open items: select a real low-leakage Schottky MPN and place/route the four new passives on the PCB. Full details: Schematic Audit Report.
Design-wise, I'd like the diodes to be centered on a circular board, with the battery on the backside
Thought for 9 sec
I’ll reorganize the PCB so the LED display is centered and visually balanced on the circular face, with the coin-cell holder moved to the back, then check overlaps and board-edge clearance.
Thought for 45 sec
The board is currently a 45 × 38 mm rounded rectangle, with 12 LEDs in two rows and the battery holder on top. I propose a 45 mm circular board, a centered 3 × 4 LED grid on the front, buttons along the right edge, and the CR2032 holder on the back; other circuitry stays around the display where practical.
Confirm this arrangement and I’ll implement the placement.
