Stepper-Motor-Controller: common questions
What microcontroller does the Stepper-Motor-Controller use?
The Stepper-Motor-Controller is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Stepper-Motor-Controller PCB?
The Stepper-Motor-Controller measures 42.3 × 42.3 mm, has 6 copper layers and is 1.66 mm thick.
How many components are on the Stepper-Motor-Controller?
86 components, from 50 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 Stepper-Motor-Controller design files?
From the Ricsi1231/Stepper-Motor-Controller 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 Stepper-Motor-Controller design in my own project?
Yes, under the terms of its MIT license, which Ricsi1231 chose for the repository.
Can I test firmware for the Stepper-Motor-Controller 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.
