Rockmd: common questions

What microcontroller does the Rockmd use?

The Rockmd is built around the STM32H723ZGTx, from the STM32 family.

How big is the Rockmd PCB?

The Rockmd measures 50 × 86 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Rockmd?

77 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rockmd design files?

From the tor1kk/rockmd repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rockmd design in my own project?

Yes, under the terms of its GPL-3.0 license, which tor1kk chose for the repository.

Can I test firmware for the Rockmd 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.
