Disabledbabyironman: common questions
What microcontroller does the Disabledbabyironman use?
The Disabledbabyironman is built around the STM32F411CEUx, from the STM32 family.
How big is the Disabledbabyironman PCB?
The Disabledbabyironman measures 28.3 × 28.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Disabledbabyironman?
18 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Disabledbabyironman design files?
From the lohhaoyuan/disabledbabyironman repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Disabledbabyironman design in my own project?
Yes, under the terms of its MIT license, which lohhaoyuan chose for the repository.
Can I test firmware for the Disabledbabyironman 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.
