Controller: common questions
What microcontroller does the Controller use?
The Controller is built around the PIC12F1501-ISN, from the PIC family.
How big is the Controller PCB?
The Controller measures 108.2 × 143.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Controller?
48 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Controller design files?
From the CarnivalBen/golden-key repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Controller design in my own project?
The repository has no license, so all rights stay with CarnivalBen. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
