About the Wifiaudio rx hardware PCB

Wifiaudio rx hardware is an open source ESP32 PCB design by BearLaboratory, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 42 × 30.8 mm, with 52 components from 25 distinct parts.

Its main chip is the ESP-32S, from the ESP32 family. Other key parts include the pcm5102a, tp4056 and AMS1117-3.3. By type, the board carries 19 resistors, 16 capacitors, 7 connectors, 4 ICs, 4 diodes and 2 switches.

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

From the project

基于ESP32的WiFi无线麦克风接收端

整个系统在组织下分为及个仓库，请根据个人的需求参考： - 语音发射端硬件 - 发射端固件 - 接收端硬件 - 接收端固件 - PC端接收服务 - PCM5102A解码验证模块

整个系统所使用的到的工具； - EDA工具使用开源免费的Kicad - 固件开发使用简单的Arduino

WiFi Audio项目的目的是DIY一个开源且便宜的无线麦克风，辅助自己在拍摄视频时的收音。项目有几个根本点： - 软件键全开源，方便大家对软硬件部分进行针对性的修改； - 整体成本尽量低，为了达到这个目的在硬件设计部分，我舍弃了很多锦上添花的硬件（比如屏幕）； - 基于WiFi，由于我个人想让麦克风能接入网络，因此抛弃了传统的UHF转而投入了WiFi的怀抱，正巧这两年芯片价格飞涨唯一还算正常的是上来乐鑫的ESP32系列芯片，价格便宜功能强大具有WiFi及蓝牙功能，因此选择它作为我们麦克的核心处理芯片。

Wifiaudio rx hardware: common questions

What microcontroller does the Wifiaudio rx hardware use?

The Wifiaudio rx hardware is built around the ESP-32S, from the ESP32 family.

How big is the Wifiaudio rx hardware PCB?

The Wifiaudio rx hardware measures 42 × 30.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wifiaudio rx hardware?

52 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 Wifiaudio rx hardware design files?

From the BearLaboratory/wifiaudio-rx-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Wifiaudio rx hardware design in my own project?

Yes, under the terms of its GPL-3.0 license, which BearLaboratory chose for the repository.

Can I test firmware for the Wifiaudio rx hardware 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.
