Usb scoring platform: common questions
What microcontroller does the Usb scoring platform use?
The Usb scoring platform is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.
How big is the Usb scoring platform PCB?
The Usb scoring platform measures 165 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Usb scoring platform?
223 components, from 96 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 Usb scoring platform 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 Usb scoring platform 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 Usb scoring platform 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.
