V0.2 Rough Draft: common questions
What microcontroller does the V0.2 Rough Draft use?
The V0.2 Rough Draft is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the V0.2 Rough Draft PCB?
The V0.2 Rough Draft measures 32.6 × 97.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the V0.2 Rough Draft?
15 components, from 14 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 V0.2 Rough Draft design files?
From the ARTS-Laboratory/In-Situ-Water-Quality-Sensor 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 V0.2 Rough Draft design in my own project?
Yes, under the terms of its CC-BY-SA-4.0 license, which ARTS-Laboratory chose for the repository.
Can I test firmware for the V0.2 Rough Draft without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
