About the 1.2-pwm led fade PCB

1.2-pwm led fade is an open source ESP32 PCB design by josh4858, published on GitHub. It is a board, with 3 components from 3 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. By type, the board carries 1 IC, 1 LED and 1 resistor.

From the project

Sunrise desk-lamp dimmer: an ESP32 fades an LED smoothly from off to full brightness and back over a continuous 3-second cycle, using PWM (LEDC) with no visible flicker or stepping.

1.2-pwm led fade: common questions

What microcontroller does the 1.2-pwm led fade use?

The 1.2-pwm led fade is built around the ESP32-WROOM-32, from the ESP32 family.

How many components are on the 1.2-pwm led fade?

3 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the 1.2-pwm led fade design files?

From the josh4858/1.2-pwm-led-fade repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the 1.2-pwm led fade design in my own project?

The repository has no license, so all rights stay with josh4858. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 1.2-pwm led fade 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.
