Serialsentinel: common questions

What microcontroller does the Serialsentinel use?

The Serialsentinel is built around the ESP32-C3-WROOM-02U, from the ESP32 family.

How big is the Serialsentinel PCB?

The Serialsentinel measures 82 × 68.9 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Serialsentinel?

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

Where can I download the Serialsentinel design files?

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

Can I use the Serialsentinel design in my own project?

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

Can I test firmware for the Serialsentinel 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.
