Skin optoelectronics module: common questions
What microcontroller does the Skin optoelectronics module use?
The Skin optoelectronics module is built around the ATtiny416, from the AVR/Arduino family.
How big is the Skin optoelectronics module?
The Skin optoelectronics module measures 20.6 × 6 mm, has 4 copper layers and is 1 mm thick.
How many components are on the Skin optoelectronics module?
77 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Skin optoelectronics module design files?
From the Roboy/roboy-skin-electronics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Skin optoelectronics module design in my own project?
The repository has no license, so all rights stay with Roboy. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Skin optoelectronics module 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.
