The final schematic cleanup is complete. I’m confirming that only the real reservoir remains and then I’ll close this phase with the mechanical go/no-go for the 25 mm prototype.

The CR1632/QFN schematic redesign is complete and ERC-clean at 68 components / 43 nets. It now uses the DW3210 QFN, TPS63900 2.7 V rail, MAX40200 reverse-current protection, switched battery monitoring, and correct RF2 termination; all charging circuitry is removed.
Blocking issue
- The only credible reservoir found is a 3.5 F, 20 × 10 × 22 mm supercapacitor. It supports the coin cell electrically but cannot fit inside the 25 mm golf-ball assembly.
- A CR1632 alone cannot reliably supply the DW3210’s UWB current peaks.
Next decision
- Use the CR1632 and external supercapacitor for a bench-only electronics prototype, or
- Return to a compact high-rate rechargeable/custom cell for the in-ball prototype.
I have paused placement rather than creating a mechanically impossible board. Please choose the bench-only CR1632 version or the in-ball high-rate-cell version.
