ESP-Smartwatch: common questions

What microcontroller does the ESP-Smartwatch use?

The ESP-Smartwatch is built around the ESP32-WROVER-E, from the ESP32 family.

How big is the ESP-Smartwatch PCB?

The ESP-Smartwatch measures 40 × 29.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP-Smartwatch?

34 components, from 20 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 ESP-Smartwatch design files?

From the Westsi/ESP-Smartwatch 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 ESP-Smartwatch design in my own project?

Yes, under the terms of its GPL-2.0 license, which Westsi chose for the repository.

Can I test firmware for the ESP-Smartwatch 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.
