BLDC PHOBOS 2021: common questions
What microcontroller does the BLDC PHOBOS 2021 use?
The BLDC PHOBOS 2021 is built around the STM32F303K8Tx_NUCLEO-F303K8, from the STM32 family.
How big is the BLDC PHOBOS 2021 PCB?
The BLDC PHOBOS 2021 measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the BLDC PHOBOS 2021?
208 components, from 101 distinct parts. The full bill of materials is listed on this page.
Where can I download the BLDC PHOBOS 2021 design files?
From the koson/3PhaseMotorDriver repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BLDC PHOBOS 2021 design in my own project?
The repository has no license, so all rights stay with koson. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BLDC PHOBOS 2021 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.
