The LPS Mini WiFi Adaptor turned into LPS WiFi! It is intended for anchors, but can also be used as a tag. This is our first untested prototype:

By soldering in all components on the bottom side of the PCB, it will hopefully be able to stream audio in two directions via WiFi. Sound files can also be stored on a Micro SD card. An OLED display can be soldered in if needed.Currently we only have a few hand built prototypes. We will come back when production is up and running.
