AxxSolder hw: common questions

What microcontroller does the AxxSolder hw use?

The AxxSolder hw is built around the STM32G431KBT6, from the STM32 family.

How big is the AxxSolder hw PCB?

The AxxSolder hw measures 39 × 71 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AxxSolder hw?

84 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the AxxSolder hw design files?

From the ITGuyFromIA2/AxxSolder_hw repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the AxxSolder hw design in my own project?

The repository has no license, so all rights stay with ITGuyFromIA2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the AxxSolder hw 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.
