    Note: No mention of hardened glass, but the Librem 5 comes with a plastic screen protector.

    Note: The Samsung S5K3L6XX is used in the Galaxy J4+, which takes decent photos according this review, but it has the Snapdragon 425 (4x 1.4GHz Cortex-A53, 28nm) which is comparable in CPU power to the i.MX 8M Quad and the J4+’s highest resolution video is 1080p at 30fps. The Samsung 13MP image sensor in the Librem 5 is capable of capturing 4K video at 30fps, but the i.MX 8M Quad has no hardware video encoder and its documentation indicates that it is only capable of encoding 1080p video at 30fps in software. There is currently no kernel support for the front and back cameras and there is only a mockup of a future camara app for the Librem 5.

Component Count

Here is the component count in the Librem 5's two printed circuit boards:

Type of component Main PCB USB PCB
Antenna connectors (ANTxxx) 3 2
Capacitors (Cxxx) 521 11
Connectors (CONxxx) 6 8
Diodes (Dxxx) 26 1
Fuses (Fxxx) 15 1
Wire links (Jxxx) 18 2

Resistors (Rxxx) 333 7
Inductors (Lxxx) 79 7
Transistors (Qxxx) 17 0
Switches (SWxxx) 5 0
Test controls (TCxxx) 15 0
Test points (TPxxx) 60 0
Test screw (TSxxx) 12 4
Test voltage (TVxxx) 39 0
Transient voltage suppressors (TVSxxx) 33 0
Integrated circuits (Uxxxx) 65 2
Crystal oscillators (Yxxxx) 10 0
Total 1259 45

If the test elements aren't included (since they are printed in the board), then the two Librem 5 boards together have 1174 components. This doesn't include the components in the two M.2 cards, which would increase the component count for the Librem 5.

It's interesting to compare the Librem 5 with the PinePhone, which has 672 components in its two PCBs (not including the test elements).

* 18 parts for the PinePhone USB-C port are labeled as Txxx in the schematic with the image of transistors, but it is possible that these are resistors and capacitors, just like in the Librem 5 schematic.

† There are 26 U/DUxxx listed in the PinePhone schematic, but the two extra are for an alternative magnetometer (U1200 / U1203) and an alternative gyroscope and accelerometer (U1202 / U1204) which are unpopulated.
