PantoGraph: common questions
What microcontroller does the PantoGraph use?
The PantoGraph is built around the ATtiny1616-M, from the AVR/Arduino family.
How big is the PantoGraph PCB?
The PantoGraph measures 13 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the PantoGraph?
30 components, from 17 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 PantoGraph design files?
From the bask185/Train-Science-DIY 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 PantoGraph design in my own project?
The repository has no license, so all rights stay with bask185. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PantoGraph 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.
