The WII project has gone through five major buoy generations. Earlier units were research prototypes; WII4 (Intel Edison-based) and WII5 (AVR/ESP32-based) have multiple production sub-types covering different deployment profiles.

  • WII1–WII3 — early research-prototype generations.
  • WII4 — Edison-era, with sub-types.
  • WII5 — current AVR/ESP32 generation, with sub-types.
WII1 to WII3

First three generations of WII buoys — early research prototypes that laid the groundwork for the production WII4 (Edison) and WII5 (AVR) designs.

WII4

Fourth-generation Edison-based WII buoy. Multiple sub-type variants.

WII5

Current-generation WII5 buoy — AVR/ESP32 main board, multiple sub-type variants.
