Analog io board: common questions

What microcontroller does the Analog io board use?

The Analog io board is built around the STM32G070RBTx (LQFP-64), from the STM32 family.

How big is the Analog io board?

The Analog io board measures 85 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Analog io board?

113 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the Analog io board design files?

From the borzeman/PzbElectronics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Analog io board design in my own project?

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

Can I test firmware for the Analog io board 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.
