Tangara is a portable, open-source music player based on an ESP32 MCU (Crowdfunding)

Tangara is a conveyable music participant that’s out to make MP3 gamers cool once more. With an iPod-inspired design and an ESP32 module at its core, Tangara presents an open-source and nostalgic option to take heed to your favourite music and podcasts.

The ESP32-WROVER-E on the core of the music participant is the primary microcontroller nevertheless it additionally includes a co-processor, a Microchip SAMD21, which is chargeable for USB communication and energy administration. We have now coated the ESP32-WROVER-KIT, a growth equipment for the ESP32-WROVER and ESP-WROOM-32 line of modules with a JTAG interface and an LCD. The Tangara music participant can output audio by means of a 3.5mm headphone jack or Bluetooth, though Bluetooth is at the moment restricted to the default SBC codec.

Tangara is the brainchild of Australian tech firm Cool Tech Zone and is aimed on the transportable media participant neighborhood at giant. That is mirrored in lots of the design decisions made by the workforce. It has a full-color, 1.8″ show and could be managed through the 2 facet quantity buttons and the big, capacitive contact wheel within the center.

This mission is totally open-source and the {hardware}, software program, and firmware are hosted on sourcehut. This implies you could change and tweak any a part of the system to fit your style, and it is usually simpler to restore, in comparison with most alternate options. Documentation for the music participant could be discovered on the cooltech.zone web site.

The firmware is written in C++17 utilizing ESP-IDF and makes use of a LevelDB-based database that imposes no restrict on the variety of tracks that may be saved. Your entire UI is written within the Lua language and the worldwide locale assist permits you to type your assortment in response to your language of selection.

Tangara launched on CrowdSupply in early February and it has already blown previous its funding objective. The music participant is priced at $249 – cheaper than the iPod Gen 1 when it launched – and there’s free delivery worldwide. Orders are anticipated to ship by September 2024.
