Encoders-LCD: common questions
What microcontroller does the Encoders-LCD use?
The Encoders-LCD is built around the ATtiny412-SS, from the AVR/Arduino family.
How big is the Encoders-LCD PCB?
The Encoders-LCD measures 100 × 76 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Encoders-LCD?
24 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Encoders-LCD design files?
From the jvegaf/R3M1XXX repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Encoders-LCD design in my own project?
The repository has no license, so all rights stay with jvegaf. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Encoders-LCD 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.
