About the RX8-7(Finished BeforeESPChange) PCB

RX8-7(Finished BeforeESPChange) is an open source ESP32 PCB design by bradport02, published on GitHub. It is a 4-layer board measuring 165.3 × 123.7 mm, with 407 components from 129 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the TDA7719, TDA7388, NJM4556AM, SI4703-C19-GM and PCM5102APWR. By type, the board carries 175 resistors, 125 capacitors, 30 diodes, 21 ICs, 18 transistors and 11 connectors.

It belongs with the audio, iot & wireless and displays & leds designs in this gallery.

From the project

An infotainment system for the Mazda RX-8 that integrates seamlessly with the climate control unit.

A full-stack aftermarket infotainment replacement for a Mazda RX-8, developed as a final-year individual engineering project (BEng Electronic Engineering, Royal Holloway University of London — First Class, dissertation graded 81%).

The system replaces the OEM head unit and integrates directly with the car's existing CAN bus, audio amplifiers, climate control unit, and CD changer — most of which use undocumented, proprietary protocols that had to be reverse engineered from scratch. It spans custom four-layer PCB design, embedded firmware, and a full Qt/QML application, and is built and…

RX8-7(Finished BeforeESPChange) design files

The KiCad project lives in the bradport02/RX8-Infotainment_System repository on GitHub; these links point at the commit this page was built from.

RX8-7(Finished BeforeESPChange): common questions

What microcontroller does the RX8-7(Finished BeforeESPChange) use?

The RX8-7(Finished BeforeESPChange) is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the RX8-7(Finished BeforeESPChange) PCB?

The RX8-7(Finished BeforeESPChange) measures 165.3 × 123.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RX8-7(Finished BeforeESPChange)?

407 components, from 129 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 RX8-7(Finished BeforeESPChange) design files?

From the bradport02/RX8-Infotainment_System repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the RX8-7(Finished BeforeESPChange) design in my own project?

The repository has no license, so all rights stay with bradport02. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RX8-7(Finished BeforeESPChange) 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.
