About the ESP32 laptop midi PCB

ESP32 laptop midi is an open source ESP32 PCB design by collaborative-music-lab, published on GitHub. It is a 2-layer board measuring 97 × 38 mm, with 19 components from 6 distinct parts.

Its main chip is the Wifiduino-ESP32S3-SMD, from the ESP32 family. By type, the board carries 8 capacitors, 6 switches, 4 diodes and 1 IC.

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

From the project

ESP32-s3 midi controller

1. The main PCB, with the ESP32 pre-soldered 2. 4 potentiometers, 2 to place on the PCB and two additional off-board potentiometers with small pcbs. 3. 4 Arcade Buttons 4. An LSM6DS3 IMU breakout board 5. An RGB LED and resistors

Make sure get your enclosure drilled for your faceplate before you mount your PCB to the faceplate in step 9!!!

1. Place two potentiometers on the PCB. Make sure they are flat. It is a good idea to place the potentiometers on a faceplate to make sure they are aligned. Solder the potentiometers in place. the potentiometers go on the opposite side of the PCB from the…

ESP32 laptop midi: common questions

What microcontroller does the ESP32 laptop midi use?

The ESP32 laptop midi is built around the Wifiduino-ESP32S3-SMD, from the ESP32 family.

How big is the ESP32 laptop midi PCB?

The ESP32 laptop midi measures 97 × 38 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 laptop midi?

19 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 laptop midi design files?

From the collaborative-music-lab/ESP_MIDI repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32 laptop midi design in my own project?

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

Can I test firmware for the ESP32 laptop midi 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.
