About the Led tube PCB

Led tube is an open source ESP32 PCB design by nichtrami, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 26.3 × 59 mm, with 13 components from 10 distinct parts.

Its main chip is the SeeeduinoXIAO ESP32S3, from the ESP32 family. By type, the board carries 5 capacitors, 3 connectors, 2 ICs, 2 diodes and 1 resistor.

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

From the project

A LED Tube that works wireless and runs on a ESP32 with Arduino Framework

The codebase builds two different devices from the same sources, selected via the DEVICEMODE build flag in platformio.ini`:

Datasheets for the components used are not redistributed in this repository. The part numbers are given in the schematics and can be looked up on the manufacturers' sites.

Each tube occupies TUBEDATASETSIZE (4) channels: effect, red, green, blue.

Led tube: common questions

What microcontroller does the Led tube use?

The Led tube is built around the SeeeduinoXIAO ESP32S3, from the ESP32 family.

How big is the Led tube PCB?

The Led tube measures 26.3 × 59 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Led tube?

13 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Led tube design files?

From the nichtrami/led_tube repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Led tube design in my own project?

Yes, under the terms of its Apache-2.0 license, which nichtrami chose for the repository.

Can I test firmware for the Led tube 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.
