ISS MD SUB: common questions
What microcontroller does the ISS MD SUB use?
The ISS MD SUB is built around the STM32F303K8Tx, from the STM32 family.
How big is the ISS MD SUB PCB?
The ISS MD SUB measures 39.6 × 64 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ISS MD SUB?
31 components, from 22 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 ISS MD SUB design files?
From the mememan5868/2026-NroboB 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 ISS MD SUB design in my own project?
The repository has no license, so all rights stay with mememan5868. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ISS MD SUB 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.
