Nexrig: common questions
What microcontroller does the Nexrig use?
The Nexrig is built around the STM32H753ZIT6, from the STM32 family.
How big is the Nexrig PCB?
The Nexrig measures 300 × 200 mm, has 6 copper layers and is 1.5582 mm thick.
How many components are on the Nexrig?
642 components, from 162 distinct parts. The full bill of materials is listed on this page.
Where can I download the Nexrig design files?
From the alanmimms/nexrig repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Nexrig design in my own project?
The repository has no license, so all rights stay with alanmimms. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Nexrig 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.
