If the test elements aren't included (since they are printed in the board), then the two Librem 5 boards 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 number of [components in PinePhone](https://wiki.pine64.org/index.php?title=PinePhone_component_list) to the Librem 5, which is a more complex device:

\* 18 parts for the PinePhone USB-C port are labeled as T*xxx* in the schematic with the image of transistors, but I suspect these are really resistors and capacitors, just like in the Librem 5 schematic. |
