***Note:*** The i.MX 8M Quad processor was flipped on the other side of the main circuit board in Dogwood, so it could dissipate heat through the back of the LCD and the phone's metal frame. The Microchip [USB2642](https://ww1.microchip.com/downloads/en/DeviceDoc/00001578D.pdf) USB 2.0 Hub & Flash media card controller should have a [QFN](https://en.wikipedia.org/wiki/Flat_no-leads_package) package, but it appears to have a [QFP](https://en.wikipedia.org/wiki/Quad_flat_package) package in the above photo. The Wolfson Media [WM8962](https://www.cirrus.com/products/wm8962-62b/) audio DAC is probably the small chip to the right of the i.MX 8M Quad processor. The Texas Instruments [BQ25895](https://www.ti.com/lit/ds/symlink/bq25895.pdf) I2C charge controller is probably underneath the metal shield near the 3-pin battery connector and the Winbond [W25Q16JVUXIM](https://www.mouser.com/ProductDetail/Winbond/W25Q16JVUXIM-TR?qs=qSfuJ%252Bfl%2Fd4%2FaGHjiPR2pw%3D%3D) TR SPI NOR Flash is probably located underneath the metal shield which is above the vibration motor.

If the test elements aren't included (since they are printed in the board), then the two Librem 5 boards together have 1174 components. In addition, the RS9116 WiFi/Bluetooth M.2 card contains 87 components and the BM818 modem M.2 card contains 6 components, so the 4 boards in the Librem 5 contain a total of 1267 components.
|
|
|
|
|
|
|
|
In comparison, the typical smartphone has between 400 and 600 components, which shows how much easier it is to design a phone with an integrated mobile SoC. The Librem 5 has 2.5 times as many components as the typical smartphone, because it uses 6 separate chips ([i.MX 8M Quad](https://www.nxp.com/docs/en/data-sheet/IMX8MDQLQCEC.pdf), [RS9116](https://www.silabs.com/wireless/wi-fi/rs9116-wi-fi-transceiver-modules), [BM818](http://www.broadmobi.com/en/module_show.php?id=18)/[PLS8](https://storage.pardot.com/128881/202595/Thales_Cinterion_PLS8_Datasheet.pdf), [Teseo-LIV3F](https://www.st.com/resource/en/datasheet/teseo-liv3f.pdf), [WM8962](https://www.cirrus.com/products/wm8962-62b/) and [bq25895](https://www.ti.com/lit/ds/symlink/bq25895.pdf)) in place of an integrated mobile SoC, plus it has extra circuitry for its hardware kill switches and the smartcard reader (which requires a separate ARM microcontroller).
|
|
|
|
|
|
|
|
It's interesting to compare the Librem 5 with the [PinePhone](https://www.pine64.org/pinephone/), which has 4 chips in place of an integrated mobile SoC. The PinePhone contains 672 [components in its two PCBs](https://wiki.pine64.org/index.php?title=PinePhone_component_list) (not including the test elements).

\* 18 parts for the PinePhone USB-C port are labeled as T*xxx* 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.

***Note:*** The i.MX 8M Quad processor was flipped on the other side of the main circuit board in Dogwood, so it could dissipate heat through the back of the LCD and the phone's metal frame. The Microchip [USB2642](https://ww1.microchip.com/downloads/en/DeviceDoc/00001578D.pdf) USB 2.0 Hub & Flash media card controller should have a [QFN](https://en.wikipedia.org/wiki/Flat_no-leads_package) package, but it appears to have a [QFP](https://en.wikipedia.org/wiki/Quad_flat_package) package in the above photo. The Wolfson Media [WM8962](https://www.cirrus.com/products/wm8962-62b/) audio DAC is probably the small chip to the right of the i.MX 8M Quad processor. The Texas Instruments [BQ25895](https://www.ti.com/lit/ds/symlink/bq25895.pdf) I2C charge controller is probably underneath the metal shield near the 3-pin battery connector and the Winbond [W25Q16JVUXIM](https://www.mouser.com/ProductDetail/Winbond/W25Q16JVUXIM-TR?qs=qSfuJ%252Bfl%2Fd4%2FaGHjiPR2pw%3D%3D) TR SPI NOR Flash is probably located underneath the metal shield which is above the vibration motor.

## Components in the WiFi/Bluetooth M.2 board
|
|
|
|
|
|
|
|
Since January 2023 all Librem 5's are shipped with the [SparkLAN WNFB-266AXI(BT)](https://puri.sm/posts/shipping-new-sparklan-wifi-cards-with-librem-5/) WiFi/Bluetooth M.2 board.
|

## Component Count
|
|

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

|
|

|**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. In addition, the RS9116 WiFi/Bluetooth M.2 card contains 87 components and the BM818 modem M.2 card contains 6 components, so the 4 boards in the Librem 5 contain a total of 1267 components.
|
|
|
|
|
|
|
|
In comparison, the typical smartphone has between 400 and 600 components, which shows how much easier it is to design a phone with an integrated mobile SoC. The Librem 5 has 2.5 times as many components as the typical smartphone, because it uses 6 separate chips ([i.MX 8M Quad](https://www.nxp.com/docs/en/data-sheet/IMX8MDQLQCEC.pdf), [RS9116](https://www.silabs.com/wireless/wi-fi/rs9116-wi-fi-transceiver-modules), [BM818](http://www.broadmobi.com/en/module_show.php?id=18)/[PLS8](https://storage.pardot.com/128881/202595/Thales_Cinterion_PLS8_Datasheet.pdf), [Teseo-LIV3F](https://www.st.com/resource/en/datasheet/teseo-liv3f.pdf), [WM8962](https://www.cirrus.com/products/wm8962-62b/) and [bq25895](https://www.ti.com/lit/ds/symlink/bq25895.pdf)) in place of an integrated mobile SoC, plus it has extra circuitry for its hardware kill switches and the smartcard reader (which requires a separate ARM microcontroller).
|
|
|
|
|
|
|
|
It's interesting to compare the Librem 5 with the [PinePhone](https://www.pine64.org/pinephone/), which has 4 chips in place of an integrated mobile SoC. The PinePhone contains 672 [components in its two PCBs](https://wiki.pine64.org/index.php?title=PinePhone_component_list) (not including the test elements).

|
\* 18 parts for the PinePhone USB-C port are labeled as T*xxx* 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.
