Ahriman: common questions
What microcontroller does the Ahriman use?
The Ahriman is built around the EFM32TG11B520F128GM64-A, from the Silicon Labs family.
How big is the Ahriman PCB?
The Ahriman measures 52.7 × 61.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ahriman?
107 components, from 44 distinct parts. The full bill of materials is listed on this page.
Where can I download the Ahriman design files?
From the matt001k/Ahriman repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Ahriman design in my own project?
The repository has no license, so all rights stay with matt001k. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ahriman without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Silicon Labs firmware against it before you order a PCB.
