OpenExcimer-Hardware: common questions
What microcontroller does the OpenExcimer-Hardware use?
The OpenExcimer-Hardware is built around the STM32G071KBT6, from the STM32 family.
How big is the OpenExcimer-Hardware PCB?
The OpenExcimer-Hardware measures 110 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the OpenExcimer-Hardware?
138 components, from 64 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 OpenExcimer-Hardware design files?
From the OSLUV/OpenExcimer-Hardware 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 OpenExcimer-Hardware design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which OSLUV chose for the repository.
Can I test firmware for the OpenExcimer-Hardware without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
