Custompcbwatch: common questions

What microcontroller does the Custompcbwatch use?

The Custompcbwatch is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Custompcbwatch PCB?

The Custompcbwatch measures 56 × 74.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custompcbwatch?

24 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Custompcbwatch design files?

From the AryanMP07/custompcbwatch repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Custompcbwatch design in my own project?

The repository has no license, so all rights stay with AryanMP07. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Custompcbwatch 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.
