- Camera Module: Integrate the IMX219 camera module (IQL-IMX219/FF). = Motion Detection: Integrate a suitable PIR motion sensor to detect motion to trigger the camera. - Lighting Adjustment: Integrate a suitable ambient light sensor that will be later used to adjust camera settings based on lighting conditions. - Power Supply: Design a power supply circuit to ensure stable operation. Choose and justify the power management components used. Use at least one switching regulator in your…

Cam Hat Case Study: common questions

What microcontroller does the Cam Hat Case Study use?

The Cam Hat Case Study is built around the ATSAMD11D14A-MUT, from the Microchip SAM family.

How big is the Cam Hat Case Study?

The Cam Hat Case Study measures 65 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cam Hat Case Study?

42 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Cam Hat Case Study design files?

From the auxren/Cam_Hat_Case_Study repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Cam Hat Case Study design in my own project?

Yes, under the terms of its MIT license, which auxren chose for the repository.

Can I test firmware for the Cam Hat Case Study without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
