+## 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.
+
+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)
