About the Esp cc dimmer PCB

Esp cc dimmer is an open source ESP32 PCB design by flaviut, published on GitHub. It is a 2-layer board measuring 68.3 × 52 mm, with 13 components from 10 distinct parts.

Its main chip is the XIAO-ESP32-C3-SMD, from the ESP32 family. Other key parts include the VEML7700-TR and LX8015. By type, the board carries 5 capacitors, 3 ICs, 2 connectors and 2 resistors.

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

From the project

A Wi-Fi constant-current LED dimmer running ESPHome.

A Wi-Fi constant-current LED dimmer running ESPHome.

Designed to clamp onto wire shelving to dim a plant grow-light string. The 3D-printed enclosure bolts to two shelf nuts that slot behind the wire grid; two M3×20 bolts and nylock nuts pinch the shelf wire between box and nuts. The knob allows offline dimming.

- 10–56 V DC, set by the NLDD-H input range (the board silk marks the 48 V design point). - At least ~2 V above the LED string's forward voltage. Read your LED strip's datasheet. - Current capacity ≥ your LED string + 50mA for the electronics.

Esp cc dimmer: common questions

What microcontroller does the Esp cc dimmer use?

The Esp cc dimmer is built around the XIAO-ESP32-C3-SMD, from the ESP32 family.

How big is the Esp cc dimmer PCB?

The Esp cc dimmer measures 68.3 × 52 mm, has 2 copper layers and is 1.600198 mm thick.

How many components are on the Esp cc dimmer?

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

Where can I download the Esp cc dimmer design files?

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

Can I use the Esp cc dimmer design in my own project?

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

Can I test firmware for the Esp cc dimmer 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.
