Hardware 4850: common questions
What microcontroller does the Hardware 4850 use?
The Hardware 4850 is built around the 511-STM32F730R8T6, from the STM32 family.
How big is the Hardware 4850 PCB?
The Hardware 4850 measures 84 × 79 mm and is 1.6 mm thick.
How many components are on the Hardware 4850?
197 components, from 63 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 Hardware 4850 design files?
From the Tecnologic/hardware_4850 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Hardware 4850 design in my own project?
The repository has no license, so all rights stay with Tecnologic. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Hardware 4850 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.
