Known limitations (carried into Rev B planning)¶
The nRF54L15 datasheet review (May 2026) identified silicon constraints affecting this revision. As the combined Battery + WiFi variant, 232203 inherits the limitations of both 232201 and 232202:
- UART0 debug (
P0.02TX /P2.07RX) is split across P0/P2 — non-functional. TX-only debug possible. - Battery inputs on P2 —
DC_PRESENT(P2.03),CHARGE_STATUS(P2.04) — must be polled. AC-loss reaction degrades from instant edge-wake to ≤1 s polling. ESP32_READY(P2.08), service button (P2.06), coexREQUEST/PRIORITY(P2.00/P2.01) — all polled, no GPIOTE on P2.
UART1 to ESP32 (P0.03/P0.04) on UARTE30 is unaffected. Addressed in the planned Rev B1 GPIO remap. See Firmware Compatibility for full impact analysis.
Rev A1 — (date unrecorded) — Superseded¶
Initial prototype build. No formal release artifacts on file in the release repository.
