Arvsom: common questions
What microcontroller does the Arvsom use?
The Arvsom is built around the STM811RW16F, from the STM32 family.
How big is the Arvsom PCB?
The Arvsom measures 55 × 40 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Arvsom?
427 components, from 67 distinct parts. The full bill of materials is listed on this page.
Where can I download the Arvsom design files?
From the antmicro/arvsom repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Arvsom design in my own project?
Yes, under the terms of its Apache-2.0 license, which antmicro chose for the repository.
Can I test firmware for the Arvsom 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.
