Open Shot Clock Controller: common questions

What microcontroller does the Open Shot Clock Controller use?

The Open Shot Clock Controller is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the Open Shot Clock Controller PCB?

The Open Shot Clock Controller measures 100 × 47.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Open Shot Clock Controller?

164 components, from 55 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 Open Shot Clock Controller design files?

From the DLaxV-Community-Projects-Hub/Open-Shot-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 Open Shot Clock Controller design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which DLaxV-Community-Projects-Hub chose for the repository.

Can I test firmware for the Open Shot 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.
