About the MusicBrain AXON - ESP32-S3 netbridge PCB

MusicBrain AXON - ESP32-S3 netbridge is an open source ESP32 PCB design by MarkWestbroek, published on GitHub under the MIT license. It is a 2-layer board measuring 70 × 45 mm, with 48 components from 31 distinct parts.

Its main chip is the ESP32-S3-WROOM-1U, from the ESP32 family. Other key parts include the W5500 and AMS1117-33. By type, the board carries 22 capacitors, 13 resistors, 4 connectors, 3 ICs, 2 switches and 2 diodes.

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

From the project

A central brain running on teensy or a lighter MCU to process any control signals (MIDI, CV, our own) into the same but adding logic, ADSRs, DCOs, CV matrices etc. to it

Praktisch: de netwerkkaart van het Cortex-systeem. Een ESP32-S3 serveert de editor-API over WiFi én bekabeld netwerk (W5500) en praat via één UART met de master-Teensy op het busboard — zo krijgen patches en instellingen het systeem in zonder USB-kabel. Plan: doc/axon-plan.md; ADR 0001/0002 beschrijven de sidecar-architectuur en de API (HTTP + WebSocket + mDNS).
