RBoard: common questions

What microcontroller does the RBoard use?

The RBoard is built around the STM32F405RGT6, from the STM32 family.

How big is the RBoard PCB?

The RBoard measures 55 × 55 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RBoard?

82 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 RBoard design files?

From the juan-LARRAYA/TPP repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the RBoard design in my own project?

The repository has no license, so all rights stay with juan-LARRAYA. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RBoard 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.
