<p>Actually, in regards to this, has anyone used a FAKE_POD_NANO that could give me some tips? I woulda waited for the Tangara to be available again but my old Rockboxed Shanling Q1 recently broke beyond repair and I needed something sooner.</p><p>The Fakepod looks COOL AS HELL but I can&#x27;t read the docs lol.

<p>Initial thoughts on the FAKE_POD_NANO:</p><p>Really solid construction so far. I&#x27;m not super worried about it breaking, and even if it did, it looks easy-ish to fix.<br>Sound quality is GREAT!! The amoled display looks super crisp too.<br>Only took maybe 15 minutes to figure out how to switch it to English.<br>Can&#x27;t figure out how OTA updates work. It connects through BT for a split second, then disconnects again. And the firmware flasher on OSHWhub requires a login to download.<br>The &quot;can only read 1 subfolder deep&quot; thing is pretty annoying.<br>AFAICT it seems to have a pretty low cap for the total number of files? If true, this is gonna be THE main problem for me… I have a lottttt of music…<br>Unsure yet if it supports playlist files? It seems to just treat whatever songs happen to be in a folder as a playlist, and has no other way to organize them. Like it can&#x27;t seem to play-all a specific artist, or even really care much about metadata in general.<br>-Documentation is verrryyyy sparse, even if you can translate it.</p><br> <a href="/tags/fakepodnano/" rel="tag">#fakepodnano</a> <a href="/tags/dap/" rel="tag">#dap</a> <a href="/tags/digitalaudioplayer/" rel="tag">#digitalaudioplayer</a> <a href="/tags/fake_pod_nano/" rel="tag">#FAKE_POD_NANO</a> <a href="/tags/esp32/" rel="tag">#ESP32</a>
