Stm32 esc: common questions

What microcontroller does the Stm32 esc use?

The Stm32 esc is built around the STM32F103CBTx, from the STM32 family.

How big is the Stm32 esc PCB?

The Stm32 esc measures 36 × 59 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32 esc?

106 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stm32 esc design files?

From the dragonlock2/kicadboards repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Stm32 esc design in my own project?

Yes, under the terms of its Apache-2.0 license, which dragonlock2 chose for the repository.

Can I test firmware for the Stm32 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.
