Tangara
Tangara is an open-hardware portable music player. It runs on an ESP32, fits in your pocket, and has a battery that lasts all day.
Source Repositories
tangara-fw: The ESP32 firmware, comprising the bulk of Tangara's functionality. This is probably the repo that you're most interested in!
tangara-hw: Sources for the entire physical device. Includes both the case/enclosure, and the PCBs.
tangara-samd-fw: Firmware for the SAMD21 co-processor that manages USB connectivity, charging, and power management of the ESP32.

We're still working on getting stuff together; please check back soon!
Thanks, Aisler!
Aisler have very generously sponsored our (final?) round of pre-production prototype boards. We've gotten all of our prototype revisons from Aisler, and we couldn't be happier with their quality. Check them out!
