Spel bldc esc: common questions

What microcontroller does the Spel bldc esc use?

The Spel bldc esc is built around the STM32F103CBTx, from the STM32 family.

How big is the Spel bldc esc PCB?

The Spel bldc esc measures 84.5 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Spel bldc esc?

91 components, from 51 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spel bldc esc design files?

From the koson/spel-bldc-esc repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Spel bldc esc 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 Spel bldc esc 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.
