VESC6 OPEN HARDWARE
About the VESC6 OPEN HARDWARE PCB
VESC6 OPEN HARDWARE is an open source STM32 PCB design by duwogus7650-ctrl, published on GitHub. It is a 4-layer board measuring 110 × 45 mm, with 118 components from 46 distinct parts.
Its main chip is the C15742, from the STM32 family. Other key parts include the C477918, C98969, C124020, C495342 and C967633. By type, the board carries 52 capacitors, 40 resistors, 8 ICs, 6 transistors, 5 connectors and 4 diodes.
From the project
Economy PCBA maufacture can be used appart from the IMU - 5 boards approx £160GBP So standard PCBA manufacture with placing the IMU costs more - 5 boards approx £200GBP

Board was designed with 2 layers initially but switched to 4 for better grounding and high current supply to fets.
Release 1 has been flashed and fully tested with all functions working as expected. High power sustained tests are yet to be done. Custom board firmware including bringup guide to come.

VESC6 OPEN HARDWARE: common questions
What microcontroller does the VESC6 OPEN HARDWARE use?
The VESC6 OPEN HARDWARE is built around the C15742, from the STM32 family.
How big is the VESC6 OPEN HARDWARE PCB?
The VESC6 OPEN HARDWARE measures 110 × 45 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the VESC6 OPEN HARDWARE?
118 components, from 46 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 VESC6 OPEN HARDWARE design files?
From the duwogus7650-ctrl/board-design 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 VESC6 OPEN HARDWARE design in my own project?
The repository has no license, so all rights stay with duwogus7650-ctrl. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VESC6 OPEN HARDWARE 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.
