About the PCB Corrected

PCB Corrected is an open source ESP32 PCB design by arnaumora, published on GitHub under the MIT license. It is a 2-layer board measuring 185 × 115 mm, with 44 components from 25 distinct parts.

Its main chip is the ESP32-S3, from the ESP32 family. Other key parts include the Antenna_NFR. By type, the board carries 21 capacitors, 10 test points, 3 modules and 1 inductor.

It belongs with the sensors, test & measurement and rf & radio designs in this gallery.

From the project

An ESP32-S3 sensor unit, built on a custom KiCad-designed PCB, estimates aircraft attitude, heading, altitude and vertical speed in real time and streams them over a 2.4 GHz RF link to a Primary Flight Display (PFD) that renders a Basic-T instrument layout with a moving map.

PCB Corrected: common questions

What microcontroller does the PCB Corrected use?

The PCB Corrected is built around the ESP32-S3, from the ESP32 family.

How big is the PCB Corrected?

The PCB Corrected measures 185 × 115 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB Corrected?

44 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB Corrected design files?

From the arnaumora/TFG-Plataforma-Instrumentacion-Avionica repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB Corrected design in my own project?

Yes, under the terms of its MIT license, which arnaumora chose for the repository.

Can I test firmware for the PCB Corrected 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.
