Bill of Materials - Jetson Orin Nano version
Note
JetBot was originally designed with Jetson Nano Developer Kit, which was discontinued.
For those newly starting, we recommend planning the JetBot assembly with Jetson Orin Nano 8GB Developer Kit.
Please note that, currently, the software for the Orin version of JetBot is still work in progress.
This page lists all the parts you need to build the open-source JetBot with the new Jetson Orin Nano 8GB Developer Kit, along with purchasing links from popular vendors.
Some of the parts are 3D printed. We provide the STL files needed to print these parts. Please see our 3d printing page for tips on printing.
