## PCB and Housing
A simple PCB to combine the u-blox SAM-M10Q, a XIAO ESP32-C5 and the screen can be found in [hardware/c_its-companion/](./hardware/c_its-companion/) including finished gerber files.
Additional hardware:
- SMD Pin-Header 8 pos.: Amphenol 10129380-908001BLF
- Snap-in stand-off 8mm: WE 702910000
(You may try to put the display lower with header Samtech TSM-108-04-T-SV and stand-off WE 702917000, but antenna needs to be plugged in before putting the display on then.)
The housing is a FreeCAD model at [hardware/housing/c_its-companion-housing.FCStd](./hardware/housing/c_its-companion-housing.FCStd), but the same folder also contains finished 3mf models that can be loaded into a 3D printer slicer.
Exports are available for:
- 2mm: no battery (just display standoffs)
- 7mm: EREMIT 654060 (6.5x40x60 mm) LiPo battery
- 9mm: Some 9x40x60 mm LiPo battery, e.g. LP803860 (2000 mAh)
The display is expected to be soldered to the pin header directly to save height.
