Initial Build: common questions
What microcontroller does the Initial Build use?
The Initial Build is built around the PIC12F1572T-I/SN, from the PIC family.
How big is the Initial Build PCB?
The Initial Build measures 112 × 47 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Initial Build?
34 components, from 21 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 Initial Build design files?
From the nfernoedge/Badge-Preprototype 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 Initial Build design in my own project?
The repository has no license, so all rights stay with nfernoedge. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Initial Build 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.
