About the Buzzer PCB V3 (rerouted traces)

Buzzer PCB V3 (rerouted traces) is an open source ESP32 PCB design by scottypres, published on GitHub. It is a 2-layer board measuring 140.7 × 74.9 mm, with 27 components from 15 distinct parts.

Its main chip is the SparkFun Thing Plus ESP32 WROOM-C USB-C, from the ESP32 family. Other key parts include the TP4057 USB-C charger and Comidox 5V Booster. By type, the board carries 8 resistors, 5 connectors, 3 transistors, 3 buzzers, 3 diodes and 2 ICs.

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

From the project

GitHub: scottypres/Arduino-Paragliding-Varios Local checkout: ~/Documents/GitHub/VarioAdafruitFeatherwing — the folder name predates the rename and is not worth changing; git doesn't care what the working directory is called.

Two separate paragliding variometers live here. They share nothing but ideas — different boards, different sketches, different PCBs. Each one keeps its firmware, KiCad projects and notes inside its own top-level folder.

Buzzer PCB V3 (rerouted traces): common questions

What microcontroller does the Buzzer PCB V3 (rerouted traces) use?

The Buzzer PCB V3 (rerouted traces) is built around the SparkFun Thing Plus ESP32 WROOM-C USB-C, from the ESP32 family.

How big is the Buzzer PCB V3 (rerouted traces)?

The Buzzer PCB V3 (rerouted traces) measures 140.7 × 74.9 mm, has 2 copper layers and is 1.5 mm thick.

How many components are on the Buzzer PCB V3 (rerouted traces)?

27 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Buzzer PCB V3 (rerouted traces) design files?

From the scottypres/Arduino-Paragliding-Varios repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Buzzer PCB V3 (rerouted traces) design in my own project?

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

Can I test firmware for the Buzzer PCB V3 (rerouted traces) 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.
