 Above the pogo pins there is a SOT-23-6 IC labeled "**LPS 5VGA2**" with a small coil next to it. I assume it's a boost converter (LP6216?), I have not measured anything yet.  Above the pogo pins there is a SOT-23-6 IC labeled "**LPS 5VGA2**" with a small coil next to it.

 To its left and right there are two unpopulated QFN‑16 footprints. \\ To its left and right there are two unpopulated QFN‑16 footprints. \\
-The back of the PCB has only the two 3.5mm headphone jacks, two side buttons, the battery connector and the 12-pin connector for the secondary PCB (with labeled pinout, nice!:). What the array of square pads might be for? There are vias for thermal dissipation of the amp, the pads are tin-plated, the battery lies on top.  But why squares? Who knows. Maybe a raster for the marker writing on it? 😅 \\+The back of the PCB has only the two 3.5mm headphone jacks, two side buttons, the battery connector and the 12-pin connector for the secondary PCB (with labeled pinout, nice!:).

 The secondary PCB has an upright mounted USB-C connector and a LPS **LP4076B** linear charger for single-cell Li-Ion and Li-Polymer batteries. The board has an unlabled IC with an etched off surface and broken out I2C header, which is next to the potentiometer setting the brightness of the LEDs ( - BTW: the potentiometer is not labeled on the case of the player, only documented in the manual) The secondary PCB has an upright mounted USB-C connector and a LPS **LP4076B** linear charger for single-cell Li-Ion and Li-Polymer batteries.
