DragonBot: common questions
What microcontroller does the DragonBot use?
The DragonBot is built around the STM32F103C8T6, from the STM32 family.
How big is the DragonBot PCB?
The DragonBot measures 136.6 × 108.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DragonBot?
70 components, from 35 distinct parts. The full bill of materials is listed on this page.
Where can I download the DragonBot design files?
From the OPRobots/DragonBot repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the DragonBot design in my own project?
Yes, under the terms of its GPL-2.0 license, which OPRobots chose for the repository.
Can I test firmware for the DragonBot 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.
