The first step in building a Frog Sensor is to get all of the parts. You can find the parts list or Bill of Materials (BOM) here.
The document linked above contains quantities and links to purchase all of the parts you'll need to build a Frog.
Note that there are several 3D printed parts that you'll need to 3D print yourself. The next section will cover that in more detail.
If you're not located in the United States, check out alternatives BOMs that are specific to your country below. The parts are the same but prices are in a local currency and links are replaced with local supplier alternatives to avoid high shipping and import fees.
If your country isn't listed, consider contributing!
