RainGauge: common questions
What microcontroller does the RainGauge use?
The RainGauge is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the RainGauge PCB?
The RainGauge measures 64 × 40.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the RainGauge?
14 components, from 10 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 RainGauge design files?
From the ARTS-Laboratory/Rain-Gauge-Sensor-Package repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the RainGauge 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 RainGauge 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.
