2026-Node: common questions
What microcontroller does the 2026-Node use?
The 2026-Node is built around the STM32F446RETX, from the STM32 family.
How big is the 2026-Node PCB?
The 2026-Node measures 37 × 63 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 2026-Node?
28 components, from 21 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 2026-Node 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 2026-Node 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 2026-Node 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.
