Questions

How big is the Aquaguard PCB?

It measures 98.7 × 55.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Aquaguard use?

70 parts, built around the ESP32-S3-MINI-1-N8, L80-R, LORA-E5-HF and ASMB-LTC3-0D335. 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 Aquaguard KiCad files?

From the Lekylouch/AquaBoard repository on GitHub, at the commit this page was made from: the board is hardware/kicad/aquaguard.kicad_pcb and its schematic hardware/kicad/aquaguard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Aquaguard design in my own project?

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