Audio&Music Mobile Devices Microchip Crowdfunding Project

Tangara is a portable music player equipped with a 3.5mm headphone jack and boasts a battery life of up to a day on a single charge. Thanks to its powerful processor, you can play any form of audio on the device. Moreover, Tangara is 100% open hardware running open-source software, meaning you can easily customize, repair, and upgrade it to play the content you want in the way you prefer.


You can listen to music, audiobooks, or podcasts on a device with a classic appearance, a familiar user interface, and the ability to protect user data privacy. Alternatively, you can choose to disassemble and reassemble it, experiment with different user interfaces, create tracker-based music, develop alarm applications, and more by adjusting the current firmware. If you're interested, you can even design a new panel with different types of displays, speakers, or jacks according to your preferences.


As mentioned, Tangara is a platform well-suited for DIY projects, and this extends beyond audio applications. For instance, the ESP32 module used in Tangara is highly popular among those interested in exploring and learning about Wi-Fi and Bluetooth connections. Additionally, it provides a full-color display, battery, and a one-touch interface, significantly enhancing the user experience.
