Questions

How big is the Temp Hum Asa V2 PCB?

It measures 100 × 121.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Temp Hum Asa V2 use?

85 parts, built around the 74HCT245, LMV358ARZ, DS3231SN# and MCP4151-104E/P. 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 Temp Hum Asa V2 KiCad files?

From the BreeJagdea/Temp_Hum_Asa repository on GitHub, at the commit this page was made from: the board is Temp_Hum_Asa_V2.kicad_pcb and its schematic Temp_Hum_Asa_V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Temp Hum Asa V2 design in my own project?

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