PB01xx: common questions
What microcontroller does the PB01xx use?
The PB01xx is built around the STM32F446RET6, from the STM32 family.
How big is the PB01xx PCB?
The PB01xx measures 69 × 51.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PB01xx?
18 components, from 13 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 PB01xx design files?
From the GOS2022/Hardware repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the PB01xx design in my own project?
Yes, under the terms of its MIT license, which GOS2022 chose for the repository.
Can I test firmware for the PB01xx 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.
