- Motor Parts
- Pololu Stepper Motor. Any NEMA 17-sized bipolar stepper motor with similar specs should work as well.
- Pololu Mounting Hub. This provides an easy mounting to the motor’s shaft. Not required if you have another method of attachment.
- Pololu DRV8834 Motor Driver Carrier. This module contains the actual motor drive and plugs into the PCB.
- RF Parts
- PCB Parts
- OSH Park can manufacture your KiCAD PCB Layout for a low cost. Our layout is available to Buy-It-Now from OSH Park for a set of 3 boards for $13.65.
- This is the Bill of Materials for building the PCB. You can order all the parts from Digikey (all parts in stock as of 4/28). Also available as a .csv.

The Spin Craft is a wireless mesh-networked motor project. This project is an open-source group collaboration intended for education and experimentation. It is named after Don Seidenspinner, the founder and host of the San Diego Hardware Hackers SIG!

Design Tools Required
- Electronics Design – KiCAD – Electronics Design Automation Suite for designing schematics and layout. Open-source, multi-platform, license-free, and supported by CERN. Download Link
- 3D Modeling – TBD. This will be used to 3D model the case for the Spincraft that will be 3D printed. Perhaps Google sketch-up, Autodesk 123D, Tinkercad. Open-source alternatives are welcome! Last time I looked over a year ago there were none that were complete or powerful enough to be really useful. We will need to generate STL files from this program.
- 3D Printing Software – Use whatever you usually use to 3D print STL files.
- 3D Printer – Used to print the 3D modeled case. If you don’t have one, get a fellow Hardware Hacker to print it up for you!
- Atmel Studio 6.2 – Used to code and debug the Spincraft processor. Visual Studio 2010 Development Environment for Atmel chips. Download Link
- SAM-ICE Programmer/Debugger for ATSAM3S. (Or Possibly this SAM & AVR Debugger) This is NOT REQUIRED, but highly recommended. You can program the ATSAM3S via USB however you won’t be able to debug the code live other than using a serial terminal with printf statements! Many group members likely have SAM-ICEs, so we may be able share or team up if you have a problem. The Atmel-ICE came out recently and looks like an even cheaper solution that supports more devices!
