Vetus: common questions
What microcontroller does the Vetus use?
The Vetus is built around the PIC18F26K80_ISS, from the PIC family.
How big is the Vetus PCB?
The Vetus measures 75 × 80 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Vetus?
43 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Vetus design files?
From the mbouyer/weatherstation repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Vetus design in my own project?
Yes, under the terms of its BSD-2-Clause license, which mbouyer chose for the repository.
Can I test firmware for the Vetus without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
