AuraForge-50X
About the AuraForge-50X PCB
AuraForge-50X is an open source ESP32 PCB design by RaviKachhwaha, published on GitHub. It is a 4-layer board measuring 100 × 80 mm, with 83 components from 48 distinct parts.
Its main chip is the ESP32-WROOM-32E-N4, from the ESP32 family. Other key parts include the TPA3116D2DADR, TPS61088RHLR, IP2312-4V35, DW01A-G and FS8205A. By type, the board carries 37 capacitors, 19 resistors, 7 ICs, 6 connectors, 6 inductors and 3 diodes.
It belongs with the iot & wireless, power & battery and audio designs in this gallery.
From the project
A 4-layer programmable PCB board audio platform featuring an ESP32 DSP core, 50Hz Wi-Fi CSI radar, 2x50W TPA3116D2 Class-D amp, hybrid dual-rail power (10A TPS61088 3.7V-to-12V boost & 12–21V DC jack), 3A USB-C fast charging, BMS protection & Cyberpunk Web HUD. This is more than an amp, a complete wireless sound computer.

(Thanks to Madhav, tty7 to review my Design and tell me some mistakes like the antenna is pleased on board without open air due to that the range of it is low after the review from them I places the antenna in open air to get full range of Bluetooth and correct Wi-Fi CSI)

AuraForge-50X: common questions
What microcontroller does the AuraForge-50X use?
The AuraForge-50X is built around the ESP32-WROOM-32E-N4, from the ESP32 family.
How big is the AuraForge-50X PCB?
The AuraForge-50X measures 100 × 80 mm, has 4 copper layers and is 1.615 mm thick.
How many components are on the AuraForge-50X?
83 components, from 48 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 AuraForge-50X design files?
From the RaviKachhwaha/AuraForge-50X 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 AuraForge-50X design in my own project?
The repository has no license, so all rights stay with RaviKachhwaha. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the AuraForge-50X 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.
