About the LazyController PCB

LazyController is an open source ESP32 PCB design by souptik-samanta, published on GitHub. It is a 4-layer board measuring 79 × 100 mm, with 42 components from 21 distinct parts.

Its main chip is the XIAO-ESP32-S3-DIP, from the ESP32 family. Other key parts include the AMS1117-3.3. By type, the board carries 11 resistors, 7 diodes, 5 LEDs, 5 capacitors, 4 transistors and 4 relays.

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

From the project

I made this so my lazyaahh doesnt have to walk upto switches

A compact WiFi-enabled relay controller built on a custom PCB. Flip switches, trigger appliances, and automate stuff — all from your phone or browser. No getting up required.

LazyController is an IoT relay board designed around an ESP-based microcontroller. It exposes relay outputs over WiFi, letting you remotely toggle lights, fans, pumps, or anything else you'd rather not walk over to.

The KiCad project lives in the souptik-samanta/LazyController repository on GitHub; these links point at the commit this page was built from.

LazyController: common questions

What microcontroller does the LazyController use?

The LazyController is built around the XIAO-ESP32-S3-DIP, from the ESP32 family.

How big is the LazyController PCB?

The LazyController measures 79 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LazyController?

42 components, from 21 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 LazyController design files?

From the souptik-samanta/LazyController 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 LazyController design in my own project?

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

Can I test firmware for the LazyController 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.
