About the ESC-Development-Board

ESC-Development-Board is an open source STM32 PCB design by 10x-Aero, published on GitHub. It is a 4-layer board measuring 66 × 61.8 mm, with 82 components from 31 distinct parts.

Its main chip is the STM32F051K8Ux, from the STM32 family. Other key parts include the DRV8300DPWR, TPS62932 and INA180B2. By type, the board carries 34 capacitors, 29 resistors, 6 transistors, 5 ICs, 4 diodes and 3 inductors.

It belongs with the dev boards & breakouts and power & battery designs in this gallery.

A 6S AM32-compatible ESC built as a proof of concept for learning how to design an ESC from scratch. It gets a motor spinning — that's about the extent of what's guaranteed. Beyond that, expect rough edges.

The design is sloppy in places. If you spot schematic, layout, or component choices that actively work against basic ESC functionality, open an issue.

The KiCad project lives in the 10x-Aero/ESC-Development-Board repository on GitHub; these links point at the commit this page was built from.

ESC-Development-Board: common questions

What microcontroller does the ESC-Development-Board use?

The ESC-Development-Board is built around the STM32F051K8Ux, from the STM32 family.

How big is the ESC-Development-Board?

The ESC-Development-Board measures 66 × 61.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESC-Development-Board?

82 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESC-Development-Board design files?

From the 10x-Aero/ESC-Development-Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESC-Development-Board design in my own project?

The repository has no license, so all rights stay with 10x-Aero. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESC-Development-Board 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.
