Due to the myriad inputs and outputs that need to be managed, the electronics of the kiosk have been split into a constellation of connected boards rather than using a single monolithic board. The scheme of connections is as follows:
Arduino Mega: This is an ATmega2560-based microcontroller, used as the central processor for the kiosk. Mega Adapter: This provides a convenient 40-pin ribbon cable connection between the Arduino Mega and the main board. It carries power from the main board to the Arduino. Main Board: The heart…

Dna puzzle electronics: common questions
What microcontroller does the Dna puzzle electronics use?
The Dna puzzle electronics is built around the ATtiny84-20PU, from the AVR/Arduino family.
How big is the Dna puzzle electronics PCB?
The Dna puzzle electronics measures 127 × 66 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dna puzzle electronics?
29 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dna puzzle electronics design files?
From the scimusmn/iowa-rover repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dna puzzle electronics design in my own project?
The repository has no license, so all rights stay with scimusmn. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dna puzzle electronics 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.
