Hardware: common questions

What microcontroller does the Hardware use?

The Hardware is built around the STM32F407VETx, from the STM32 family.

How big is the Hardware PCB?

The Hardware measures 164.6 × 260.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hardware?

181 components, from 58 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hardware design files?

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

Can I use the Hardware design in my own project?

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

Can I test firmware for the Hardware 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.
