Aif io: common questions

What microcontroller does the Aif io use?

The Aif io is built around the STM32F405RGTx, from the STM32 family.

How big is the Aif io PCB?

The Aif io measures 60 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Aif io?

78 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Aif io design files?

From the hcmos/aif-io_pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Aif io design in my own project?

The repository has no license, so all rights stay with hcmos. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Aif io 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.
