Esp32 smart clock: common questions

What microcontroller does the Esp32 smart clock use?

The Esp32 smart clock is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Esp32 smart clock PCB?

The Esp32 smart clock measures 104.5 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32 smart clock?

68 components, from 38 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 Esp32 smart clock design files?

From the rokube015/esp32_smart-clock 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 Esp32 smart clock design in my own project?

Yes, under the terms of its Apache-2.0 license, which rokube015 chose for the repository.

Can I test firmware for the Esp32 smart clock 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.
