Virtual scoring box: common questions
What microcontroller does the Virtual scoring box use?
The Virtual scoring box is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.
How big is the Virtual scoring box PCB?
The Virtual scoring box measures 120 × 85 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Virtual scoring box?
142 components, from 54 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 Virtual scoring box design files?
From the AndrewCraswell/agency 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 Virtual scoring box design in my own project?
Yes, under the terms of its MIT license, which AndrewCraswell chose for the repository.
Can I test firmware for the Virtual scoring box 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.
