About the Quake sensor PCB

Quake sensor is an open source ESP32 PCB design by ismailcelik-tr, published on GitHub. It is a 2-layer board measuring 65 × 58 mm, with 54 components from 25 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N8, from the ESP32 family. Other key parts include the ADXL355BEZ, AP2112K-3.3, MCP73831-2-OT and USBLC6-2SC6. By type, the board carries 21 capacitors, 16 resistors, 5 ICs, 4 connectors, 3 diodes and 2 switches.

It belongs with the sensors, iot & wireless and power & battery designs in this gallery.

Quake sensor: common questions

What microcontroller does the Quake sensor use?

The Quake sensor is built around the ESP32-S3-WROOM-1-N8, from the ESP32 family.

How big is the Quake sensor PCB?

The Quake sensor measures 65 × 58 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quake sensor?

54 components, from 25 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 Quake sensor design files?

From the ismailcelik-tr/quake-sensor 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 Quake sensor design in my own project?

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

Can I test firmware for the Quake sensor 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.
