IntAna: common questions
What microcontroller does the IntAna use?
The IntAna is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the IntAna PCB?
The IntAna measures 66.2 × 63.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the IntAna?
69 components, from 28 distinct parts. The full bill of materials is listed on this page.
Where can I download the IntAna design files?
From the radioelf/OpenPlc repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the IntAna design in my own project?
The repository has no license, so all rights stay with radioelf. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the IntAna 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.
