About the Wisweep PCB

Wisweep is an open source ESP32 PCB design by slimcdk, published on GitHub under the MIT license. It is a 4-layer board measuring 38.5 × 39.2 mm, with 54 components from 26 distinct parts.

Its main chip is the ESP32-C6-MINI-1/U, from the ESP32 family. Other key parts include the LMR16006YQ3, TMC5240-TSSOP38 and AS5047D. By type, the board carries 20 capacitors, 12 resistors, 7 connectors, 4 ICs, 4 jumpers and 4 diodes.

It belongs with the robotics & motion and iot & wireless designs in this gallery.

From the project

ESP32 and Trinamic based closed-loop stepper controller

Feel free to support me and the development I do!

Compact WiFi and Bluetooth (5.0) / ZigBee NEMA17 stepper controller featuring stall detection and ultra silent operation. Supply 5-36V upto 3A.

Revisions are controlled through git tags such any production easily can be traced back to a commit containing everything. Complete sets of compatible schematics, PCB layouts, documentations, 3D models etc will all stay together under same tag in the source history.

Wisweep: common questions

What microcontroller does the Wisweep use?

The Wisweep is built around the ESP32-C6-MINI-1/U, from the ESP32 family.

How big is the Wisweep PCB?

The Wisweep measures 38.5 × 39.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Wisweep?

54 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Wisweep design files?

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

Can I use the Wisweep design in my own project?

Yes, under the terms of its MIT license, which slimcdk chose for the repository.

Can I test firmware for the Wisweep 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.
