Product families

EverTag is one platform with three product lines. They share some hardware and firmware concepts, but documentation and design proposals are organized per product line.

Shared platform ≠ shared product docs

230220 is the GPIO pin-out reference for all nRF54 boards, and the Tag/Anchor firmware build covers 230220 + 232200 + 232201. That does not mean Station and Tag share one proposal document or one overview page. When in doubt, split by product line and cross-link.

Products and article numbers

Product line PCB articles Power Typical docs path
EverTag Station (nRF54) 232200–232204, 232210–232211 Wall (Power Base → 5V) station/
EverTag Tag nRF54 230220+ Battery tag-nrf54/
EverTag Tag nRF52 (legacy) 230200, 230202, 230204, 230206 Battery tag-nrf52/
Article Product Role
232200–232204 Station Connectivity Module base (shared outline, variant BOM)
232210–232211 Station LTE extension (stacks on base)
232506 Station Enclosure (mechanical — not a PCB article)
230220 Tag nRF54 Tag base — pin-out reference for nRF54 family

Shared vs product-specific

Topic Shared across nRF54 family Product-specific
GPIO pin directions and mux rules Yes — Firmware Compatibility Function per variant (ACC on Tag, coex on gateway, …)
PAN611 module Same module on 230220 and 232200–232204 Layout context (coex pads on gateway, ACC/NFC on Tag)
Tag/Anchor firmware build 230220, 232200, 232201 Gateway build is Station-only (232202+)
ST25DV04K NFC All nRF54 boards Antenna coil layout differs Tag vs Station
Rev B1 ECN-01 — GPIO remap One respin, all six base PCBs Two proposal entry points (Station full map + Tag summary)
Enclosure mounting (screw / slots) — Station only (232200–232204, 232210, 232506)
PAN611 antenna keep-out size Same datasheet rule (5.0 × 3.25 mm) Two proposals — verify routing per product

Field Values Purpose
ecn_id e.g. ECN-02 Engineering change number — cite as Rev B1 ECN-02 in email, PO, and release packages
product_family station, tag-nrf54, cross-family Primary doc home; cross-family = full technical doc with product-specific summaries elsewhere
change_type gpio, mechanical, rf-layout, footprint, … Helps agents pick the right template and reviewers
affects PCB article list In scope
excludes PCB article list Prevents accidentally documenting Tag changes under Station (or vice versa)

Checklist before writing a proposal

  1. Which product line (Station / Tag nRF54)?
  2. Which article numbers go in affects?
  3. What goes in excludes?
  4. Does the other product need a separate file with a cross-link?
  5. If both products ship in the same B1 respin — note that in each doc; do not merge scope tables across products unless verification is identical.
