Hagent: common questions

What microcontroller does the Hagent use?

The Hagent is built around the STM32H743ZIT6, from the STM32 family.

How big is the Hagent PCB?

The Hagent measures 85 × 65 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hagent?

71 components, from 39 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 Hagent design files?

From the changgeruoxiao/hagent 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 Hagent design in my own project?

Yes, under the terms of its MIT license, which changgeruoxiao chose for the repository.

Can I test firmware for the Hagent 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.
