Questions

How big is the ThermalV3 PCB?

It measures 90.3 × 94.6 mm and has 4 copper layers, 0.62 mm thick.

What parts does the ThermalV3 use?

126 parts, built around the MIMXRT1062DVJ6B, MKL02Z32VFG4, STM32F401CBU6 and PAM2305DGFADJ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the ThermalV3 KiCad files?

From the moro696/thermal_camera repository on GitHub, at the commit this page was made from: the board is thermalV3_kickad/thermalV3.kicad_pcb and its schematic thermalV3_kickad/sensor board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ThermalV3 design in my own project?

Its repository states no licence, so its author keeps all rights: ask moro696 before reusing the design.
