Small ESP32 SR-WLED Controller

A small LED controller that runs WLED-Sound Reactive. Supports 5-24V analog and addressible lights.

Interactive BOM

Features:

  • 4 Analog Channels (Up to 3A each) for analog RGB and RGBW LED strips
  • 2 Addressible Channels, level shifted to 5V to support single data line and dual data line addressible LED strips.
  • Variable Input voltage from 5-24V (Input voltage must match the LED strip voltage)
  • Controlled with an ESP8266 running WLED and connected over Wi-Fi
  • Panelized in a 2x2 panel of 50x50mm for minimal fabrication costs at JLCPCB
  • BOM cost is kept low at around $6 per board

Pinout

Pinout

Bring-up and Usage

  • All front components should be soldered by JLCPCB.
  • Flip the board and solder the ESP32 WROOM chip.
  • Attach the programming device onto the mezzamine connector on the top front of the board
  • Program the ESP32 with WLED
  • Unplug the programming header
  • Solder on lights and a power lead
  • Connect to the ESP's Wi-Fi network and turn on the lights!

Questions

How big is the ESP32-Small SRWLED panelization PCB?

It measures 41.7 × 43.1 mm and has 4 copper layers, 1.58 mm thick.

What parts does the ESP32-Small SRWLED panelization use?

188 parts, built around the ESP32-WROOM-32D, TPS54202DDC, AO3400A and 78L05G-AB3-R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the ESP32-Small SRWLED panelization KiCad files?

From the wszeto9/Small-ESP32-SR-WLED-Controller repository on GitHub, at the commit this page was made from: the board is PCB/ESP32-Small-SRWLED_panelization.kicad_pcb and its schematic PCB/ESP32-Small-SRWLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ESP32-Small SRWLED panelization design in my own project?

Its repository states no licence, so its author keeps all rights: ask wszeto9 before reusing the design.
