GimbalFOC: common questions

What microcontroller does the GimbalFOC use?

The GimbalFOC is built around the MOUDLE14P-SMD-2.54-21X17.8MM, from the ESP32 family.

How big is the GimbalFOC PCB?

The GimbalFOC measures 47 × 47 mm, has 4 copper layers and is 1.69 mm thick.

How many components are on the GimbalFOC?

28 components, from 20 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 GimbalFOC design files?

From the avaninder/GimbalFOC 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 GimbalFOC design in my own project?

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

Can I test firmware for the GimbalFOC without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
