Librem 5 [Dogwood's circuit boards](https://puri.sm/posts/librem-5-dogwood-update-3/) with [labeled components](https://forums.puri.sm/t/where-components-are-placed-on-the-librem-5-boards/13705/7):

***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.
