About the Aeropod2 PCB

Aeropod2 is an open source ESP32 PCB design by eyendamuri, published on GitHub. It is a 4-layer board measuring 41 × 90.2 mm, with 66 components from 35 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the TP4056-42-ESOP8, AMS1117-3.3, MPR121QR2, PCM5102A and CP2102N-AXX-XQFN20. By type, the board carries 27 capacitors, 17 resistors, 7 ICs, 5 connectors, 5 diodes and 2 switches.

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

From the project

An esp32 based mp3 player with the ability to play video too.

A handheld music player built from scratch: custom hardware, custom firmware, custom everything.

aeropod is an iPod-inspired portable media player built around an ESP32. It has a capacitive click wheel, a 240×320 colour display, and plays music three different ways: local files from a microSD card, Spotify (both as a Spotify Connect speaker and through the Web API), and as a Bluetooth speaker over A2DP. It even plays MJPEG video. Everything runs on a custom 4-layer circuit board I designed, inside a 3D-printed case.

Aeropod2: common questions

What microcontroller does the Aeropod2 use?

The Aeropod2 is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Aeropod2 PCB?

The Aeropod2 measures 41 × 90.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Aeropod2?

66 components, from 35 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 Aeropod2 design files?

From the eyendamuri/aeropod 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 Aeropod2 design in my own project?

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

Can I test firmware for the Aeropod2 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.
