Oshwi board is the official pet at Bricolabs OSHWDem. Designed by Gustavo Reynaga to the OSHWDem 2017 edition, it is a lovely badget running with an ESP-12e module, 5 neo-pixels and a user button.
AFOB is another firmware to load in the Oshwi heart, intented to be extensible and coded certainly to consume current as low as possible.
