Tangara is a portable music player featuring a 3.5mm headphone jack and offers up to a full day of battery life on a single charge. Powered by a robust processor, it supports all audio formats, ensuring you can enjoy a wide range of media. Additionally, Tangara is entirely open hardware running open-source software, providing you with the flexibility to customize, repair, and upgrade the device to suit your needs and preferences.

 

Enjoy music, audiobooks, or podcasts on a device that combines a classic design with a user-friendly interface, while safeguarding your privacy. Alternatively, you can disassemble and reassemble Tangara, experiment with different interfaces, create tracker-based music, develop alarm applications, and more by modifying the current firmware. If you’re feeling creative, you can also design a new panel with custom displays, speakers, or jacks to match your unique preferences.

 

As previously mentioned, Tangara is an ideal platform for DIY projects, extending beyond just audio applications. The ESP32 module inside Tangara is particularly popular among tech enthusiasts exploring Wi-Fi and Bluetooth connectivity. Moreover, it comes with a full-color display, battery, and a one-touch interface, greatly enhancing the overall user experience.
