1. Go to the folder PCB/Production Files

2. Find the zip file named ES01mainPCB-vxx.zip

3. Upload the zip file to JLCPCB (or your preferred PCB manufacturing site), DO NOT expand the file

4. If you are using JLCPCB, follow these next instructions:

2. Set Substrate Type to 25um dielectric thickness

4. Leave Dimensions unchanged (They should be greyed out anyways)

6. Leave Different Design and Delivery Format unchanged

Triangulate-ES 01-Watch: common questions

What microcontroller does the Triangulate-ES 01-Watch use?

The Triangulate-ES 01-Watch is built around the ESP32-S3, from the ESP32 family.

How big is the Triangulate-ES 01-Watch PCB?

The Triangulate-ES 01-Watch measures 82.8 × 33 mm, has 4 copper layers and is 0.199999 mm thick.

How many components are on the Triangulate-ES 01-Watch?

125 components, from 43 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 Triangulate-ES 01-Watch design files?

From the sandgum/Triangulate-ES_01-Watch 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 Triangulate-ES 01-Watch design in my own project?

The repository has no license, so all rights stay with sandgum. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Triangulate-ES 01-Watch 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.
