Nixie-Clock: Controller: common questions

What microcontroller does the Nixie-Clock: Controller use?

The Nixie-Clock: Controller is built around the ESP32-DEVKITC-V4, from the ESP32 family.

How big is the Nixie-Clock: Controller PCB?

The Nixie-Clock: Controller measures 228.6 × 69.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nixie-Clock: Controller?

63 components, from 26 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 Nixie-Clock: Controller design files?

From the konradmoesch/nixie-clock 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 Nixie-Clock: Controller design in my own project?

The repository has no license, so all rights stay with konradmoesch. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Nixie-Clock: Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
