About the ESP32S3PD15W PCB

ESP32S3PD15W is an open source ESP32 PCB design by robertxdx, published on GitHub. It is a 4-layer board measuring 60 × 50 mm, with 42 components from 20 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N4, from the ESP32 family. Other key parts include the USBLC6-2P6, AP63203WU-7 and SN74HC125PWR. By type, the board carries 14 capacitors, 8 resistors, 5 connectors, 5 switches, 5 diodes and 4 ICs.

It belongs with the dev boards & breakouts and power & battery designs in this gallery.

A 15 W USB-C powered ESP32-S3 LED-strip controller and development board.

A 15 W USB-C powered ESP32-S3 LED-strip controller and development board.

ESP32S3PD15W is a compact ESP32-S3-WROOM-1 board built to drive a 144-LED WS2812B strip while still behaving like a practical development platform. It prioritizes power delivery over the usual low-current dev-board formula: USB-C input, an efficient buck converter, level-shifted 5 V data outputs, and accessible GPIO for experiments.

The KiCad project lives in the robertxdx/ESP32S3PD15W repository on GitHub; these links point at the commit this page was built from.

ESP32S3PD15W: common questions

What microcontroller does the ESP32S3PD15W use?

The ESP32S3PD15W is built around the ESP32-S3-WROOM-1-N4, from the ESP32 family.

How big is the ESP32S3PD15W PCB?

The ESP32S3PD15W measures 60 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32S3PD15W?

42 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the ESP32S3PD15W design files?

From the robertxdx/ESP32S3PD15W repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ESP32S3PD15W design in my own project?

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

Can I test firmware for the ESP32S3PD15W 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.
