Untitled: common questions
What microcontroller does the Untitled use?
The Untitled is built around the STM32F103RCT6, from the STM32 family.
How big is the Untitled PCB?
The Untitled measures 35.2 × 21 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Untitled?
14 components, from 12 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 Untitled design files?
From the fernandezdelpeloso/stm32-nixie-clock repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Untitled design in my own project?
The repository has no license, so all rights stay with fernandezdelpeloso. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Untitled without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
