SchrackCounter: common questions
What microcontroller does the SchrackCounter use?
The SchrackCounter is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the SchrackCounter PCB?
The SchrackCounter measures 98.5 × 88.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the SchrackCounter?
69 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 SchrackCounter design files?
From the bismarx-v1/SchrackProjects 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 SchrackCounter design in my own project?
The repository has no license, so all rights stay with bismarx-v1. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SchrackCounter 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.
