DEVboard1: common questions

What microcontroller does the DEVboard1 use?

The DEVboard1 is built around the STM32F103CBT6, from the STM32 family.

How big is the DEVboard1 PCB?

The DEVboard1 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DEVboard1?

170 components, from 61 distinct parts. The full bill of materials is listed on this page.

Where can I download the DEVboard1 design files?

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

Can I use the DEVboard1 design in my own project?

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

Can I test firmware for the DEVboard1 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.
